Tac

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.” Extremely context-dependent, because apparently language needed another word for “what the fuck are you doing?”
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.”

Tac-Yack 

A Tac-Yack (Tactical Yack) is the act of expelling alcohol or food from the body via the mouth for tactical reasons. Such tactical reasons may include but are not limited to:
1. During Boat Races where you do not wish to get too drunk too quickly in order to win subsequent boat races.
2. During an all-you-can-eat buffet where you realize that you have eaten too much of the appetizers and cannot eat the delicious main course meals unless you empty your stomach.

Fred tac-yacked all over the floor of his ex-girlfriend's car. He then proceeded to break into her house and steal all of her jewelry.
