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.
