Beast Mode

Disappearing to actually work out in the gym while your whack buddies hang out on the elliptical.

I was in Beast Mode while gonzo and bravo were exercising with fat navy women.

nibba, beast mode

this means major homicide is about to happen, nibba ( gay human being ) and beast mode ( being a furious human being ) do not go well together and ends up in men being seks'd horribly, please stay away and run whenever you hear this word.

NIBBA, BEAST MODE: ACTIVATE
Oh no! run or you will be pregnant
*teleports behind you* too late, sorry kiddo but you're within my reach, nothing personal.
