Yeet is an expression of excitement, usually screamed as a man ejaculates, but sometimes used by gamers when they win something.
"During sex, Darren suddenly scream 'yeet yeet!' as he orgasmed."
"I won the fight in Fortnite and ended up screaming 'yeet!' so loud that my neighbours heard me."
This fake word is the newest addition to the millennial culture. It is very difficult to find a comment thread where this fake word isn’t used. It seems to be used to express shock and amazement.
Dude 1: whoa!
Dude 2: what the fuck was that? We’re millennials, we are supposed to say “yeet” now. We must act like all the other dumbasses our age.
