I kicked him in the bully bag and he went down like a two-bit whore.
Bully-fart bag
a bag in which a coal sample is put in, but instead of having coal in there you take it and put it up to your ass and fart. then you take it and put it in someone's face and ask them if they know the bully-fart man.
Man alive! that was the sickest bully-fart bag i ever smelt!
