Some made up slur that 1st graders blurt through their pathetic, little,disgusting, pee pee littered mouth when they have nothing to say in an argument.
Man Poo is a drunk-like persona a person can possibly have while completely smashed.
this person will sing songs from the 30's to 70's and act as if they are really recent. they will also do crazy things eg. Skateboard nude while drunk, or do a handstandagainst a wall, pass out... but stay in handstand position.
