A condition characterized by frequent and uncontrollable urges to smack/grab/pinch or otherwise interact with butts.

He was quite offended that I pinched his ass until I calmly explained I had butt-turrets.

tarrets of the butt 

When you are farting uncontrollably breathing from your butthole. (Farting)

*farts*

"Dude! Stop giving me the sass from your ass!"

"I'm sorry bro! I suffer from tarrets of the butt!"
