Unc

Short for Uncle, means they’re old.

Usually (and ironically) used by Gen Z against Old Heads who don’t act their age, or as a joke when someone is older than you.

Old guy: “YOU HAVE NO IDEA HOW GOOD TIM DUNCAN WAS!!”

Some dude: “Yo chill unc u too old for this”

Guy: “I’m 20”
Guy 2: “damn unc u old”
