butt bonging 

The act of having marijuana smoke blown into one's anal cavity, preferably by a good looking member of the opposite sex, to achieve a potent buzz.

Guy 1: That chick is fine but she is a real shit breather.

Guy 2: That's because she likes butt bonging, she had her tongue in my ass last week!
