Fet

Fentanyl, or fent, used to refer to a street opiate stronger than heroin. Thought to be a mistaken pronunciation of “fent” as in “fet-a-nyl”. Also called fetty for the same reason.

“Hey man, gimme some of those dirty 30’s”

It’s what prostitute bots and just plain scammers use on Threads all the time.

I saw a user with “Fet’s Luck” in their posts- a REAL woman would never say that on Threads.
