bum river 

After suffering from bum dew for a prolonged period, a small stream or river can form, know as a bum river. Light coloured trousers (pants if you're American) should be avoided.

A bum river can sometimes be seen on leather car seats on a hot day or when a lard arse (somebody who regularly attends weight watchers and McDonalds) attempts to exercise.

reverse titty fuck bum-brow

A variation on the classic titty-fuck.

Start in titty fuck position then stand up, lift one leg and flip that bitch round! Now squat on her face and proceed to rub your penis between her tits while she gives you a rim job.

Guy 1: That bitch thought she could get away with a regular titty fuck, but I spun that bitch round!
Guy 2: Did she eat your ass?
Guy 1: You know it!
Guy 2: Reverse titty fuck bum-brow?
Guy 1: Hell yeah!
