Grudge Fart

A special type of gaseous leak from ones ass that heads straight for ones own nasal cavity very fast. As if the fart Is going to give you a piece of his mind for birthing him.

I pulled off my covers only to be greeted by a grudge fart making me and my friends gag.

"Dude I swear that fart has it out for me! Must've been a grudge fart."
