What else does slime mean?

What’s up, slime? Slime is slang for a (usually male) “friend,” often used as a term of address, like dude or bro.

Where does slime come from?

The slang term slimenot to be confused with the green goop of 1990s Nickelodeon fame–was popularized in 2010 by rapper Vado, and it’s used in the same way you might use bruh, homie, or, over in the U.K., mate.

Vado is a big fan of the word: he has used it in the title of five albums and throughout his lyrics. On his 2010 debut album Slime Flu, Vado used slime in the song “Snapped” to refer to his friends: “Light a 50, sit back in the cranberry 550 / My slimes with me, this chick money hungry just like Whitley.”

Vado credits, however, fellow New York rapper N.O.R.E. as the originator of the slang. Why slime? It appears just to be an idiosyncrasy, although it does follow in the tradition of negative words becoming positive in slang (cf. bad, sick, ill, wicked).

Sure enough, N.O.R.E. used slime in the title of two songs in his 2002 album God’s Favorite. In those songs, N.O.R.E. used the word as an affectionate term when talking to a friend. Specifically, N.O.R.E. calls rapper Nas slime in “Hit Me Slime,” which would technically make Nas the original slime, as this was the first use of slime in any of N.O.R.E’s albums.

N.O.R.E. also often uses slime on his social media channels and has stated that he is the inventor of the slang.

How is slime used in real life?

N.O.R.E. still remains a fan of the slang.

Other rappers have also adopted slime in the 2000s, including (outside Vado) Young Thug, who has used it in the title of albums (Slime Language) and mixtapes (Slime Season). Drake has also used slime, further helping to popularize the slang.

The non-rappers among us also use the word when giving shoutouts to the slimes in our lives.
