Back Flush

Mostly used in the fag community, it is where two men touch their penises together so the pee holes line up and the fore skin is pulled together ( best with one uncircumcised penis and one circumcised ) Then they piss inside of each other's pee hole thus back flushing the penis.

Hey bro, you wanna back flush each other tonight after dinner.

the back of the bus is the best part of the bus, as many cool people like to chill and relax there, away from the annoying people that dont like them.
