A PG-13 Fuck yeah. It can be used for any “motherfucker” situation.
A fill-in for an awkward moment of silence when nobody knows what to say.
Can also be used to refer to a beautiful older woman in a situation where you want to be incognito with your homie.
On rare occasions, it may be yelled during ejaculation.
A man walks into a bar, orders a shot of tequila and slams it immediately. He then slams down the shot glass and yells “mother boom!”
