What Does "Slatt" Mean?

"Slatt" is a greeting and an expression of loyalty that came out of Atlanta rap, popularized by Young Thug. Wiktionary records it as an acronym of "slime love all the time" or "slime life all the time," and defines it as an interjection expressing affection between friends.

If that sounds imprecise, that is because the word is imprecise on purpose. It is not a noun with a fixed referent. It is closer to a salute.

What slatt actually does in a sentence

Wiktionary files it as an interjection, which is the correct grammatical drawer. Interjections carry feeling rather than information. "Amen" is an interjection. So is "cheers." So is "salute."

That means slatt has no single translation. It opens a message, closes a message, punctuates a hug, confirms agreement, and signs off a verse. In every one of those positions the content is roughly the same: we're good, I'm with you, that's my people.

Which is why the search results for this word are such a mess. People go looking for a definition and find twelve slightly different ones, because everyone is describing a different position in the sentence. The word did not change. The context did.

What does slatt stand for?

Wiktionary's entry gives two expansions and refuses to pick: "slime love all the time" or "slime life all the time."

That refusal is the honest position, and we are keeping it. The two versions differ by one word, they are both widely repeated, and neither has a documented first citation that settles it. Anyone telling you with total confidence which one is correct is guessing with more conviction than the evidence supports.

Both expansions do agree on the load-bearing part. Whatever the second word is, the first is slime, and that is where the actual etymology lives. We break that down separately in our guide to what "slime" means in rap, because it is a longer story with a New York chapter most people skip.

You will also find sources online expanding the acronym as "Young Slime Life" or "Young Stoner Life." Those are readings of the label initials YSL rather than of the word slatt, and conflating the two muddies both. Young Stoner Life Records is the label Young Thug founded in 2016 with 300 Entertainment. That is a company name. Slatt is a word people say.

Did Young Thug ever explain it himself?

This is the part most articles quietly skip.

Wiktionary credits Young Thug with coining and popularizing the word, and his catalog backs that up: slatt appears throughout his music and his affiliated artists' music, often as an ad-lib rather than a lyric. If you want the mechanics of how a short vocal like that gets layered around a main vocal, that's covered in our breakdown of rap ad-libs.

What we could not find, after searching for it specifically, is a well-documented interview where he sits down and spells out the acronym in his own words. Plenty of secondary sources assert the expansion. None of the ones we checked trace it to him saying it on record.

So here is the accurate version, hedged the way it should be: the acronym is widely attested and appears in a lexicographic source, the attribution of the word to Young Thug is well established, and the specific expansion is not artist-confirmed as far as we can document. If that changes, this page changes.

The Atlanta context

The word travels with a scene. Young Stoner Life launched in 2016, and the label's 2018 compilation Slime Language debuted at No. 8 on the Billboard 200 with 41,000 album-equivalent units, followed by Slime Language 2 reaching No. 1 in April 2021. That is a lot of national exposure for a shared vocabulary in a short window.

XXL's history of the term traces the broader "slime" family through hip-hop and notes the snake emoji becoming the unofficial visual shorthand for it. Young Thug leaned into that imagery hard, announcing Slime Language by sending music publications live pet snakes along with a booklet of the artists involved. Say what you want about the press strategy. It communicated the brand.

Rap has always turned affiliation into vocabulary and vocabulary into names, which is a pattern we trace in our piece on where rapper nicknames come from. Slatt is that process happening in real time and in public.

The other slatt, from 1877

Here is the detail nobody puts in the meme captions. "Slatt" was already an English word, and it has nothing to do with any of this.

Wiktionary's first etymology, entirely separate from the slang one, defines slatt as a stone slab used as a veneer for coarse masonry, citing Knight's American Mechanical Dictionary of 1877 and Webster's Revised Unabridged Dictionary of 1913. It comes from "slat," a strip of board.

There is no line of descent between a Victorian masonry term and a modern Atlanta interjection. Two words, same spelling, separate lives. It is the kind of coincidence that would ruin a lesser etymology and only makes this one funnier.

How the word got out of rap

The spread followed the usual route: records first, comment sections second, everyone's cousin third.

The word appears across a wide slice of late-2010s rap, and from there did what internet-legible slang does. Short, punchy, easy to type, no clear literal meaning to trip over. Words that survive the jump to general slang are almost always ones you can use without understanding, and slatt qualifies.

That is also the reason the definition drifted. A lot of people using it now encountered it as a sound before they encountered it as a word, the same way plenty of people say a phrase from a song without knowing it was ever an acronym. Knowing the origin is not required to use it correctly. It is just more interesting.

Slatt, slime, slatty: telling them apart

Slime is a noun. Someone can be your slime, the way someone can be your brother.

Slatt is an interjection. You say it. You do not usually apply it to a person.

Slatty is the adjectival form that follows the same pattern English uses everywhere, the way "salt" gives you "salty." It is also used as a term of address in songs, which is exactly the kind of drift you would expect once a word is common enough to bend.

None of these are technical terms and none of them have a governing body. If you want a corner of rap vocabulary where the definitions actually are precise and countable, that would be the musical side, and our explainer on what "bars" means in rap starts there.
