Gravy boat
The act of farting and having said fart travels over the taint/gooch and for males this fart splits and travels on each side of the testicles and towards freedom. For females it may pass over the beef curtains and to freedom or get trapped inside to live on only to be reborn into the dreaded queef.
I had a severe case of swamp ass, farted on my leather seat and ended up gravy boating myself. It was weird like climbing the rope in gym class.
