The act of being motha-like. Or going to the SLC and enjoying the fact Stalin wore their suit on the awards day and also getting freaked the hell out by that crazy bitch at subway and wearing powersuits, and constantly cursing, and having a hand motion to say 'MOTHAA' to and being freaked out by the GRUDGE!
TOSHIO IS IN YOUR CORNER!
