mic up 

a tern used by (usually) robloxians. when someone says this to you, most times out of 10, they are trying to pack you. if not, someone is just trying to chill in a call with you. micing up is like a less dominate version of squaring up, but they are pretty much the same, you find your opponent, then pack until someone wins.

person 2: bet mic up
person 1: bet, example#0000
