To act goofy, annoying, unserious,
weird, or deliberately irritating for no real reason. Can also mean trolling, messing around, doing too much, or just behaving in a way that feels vaguely “tac.”
Basically, if somebody is goofing, trolling, annoying you, moving
weird, being unserious, or just doing some
bullshit, they’re tacing.
Examples:
“Why are you tacing around rn?”
“Stop being tac.”
“He been on some tac shit all day.”
“You’re actually tacing me right now.”
“That whole situation was tac.”
“Bro is a tac.”
You
don’
t even realize how embarrassing you are, you just keep tacing around like
people actually enjoy having you there.”
