Dorito back

A Dorito back is a back consisting of huge fucking lats and wide shoulders, making the owners back look like a Dorito. Those with smaller waists may achieve this easier than those with larger ones, however even a person with a chunky waist can have a Dorito back, if the shoulders and lats have good enough proportion.

Did you see the Mr. Olympia?
Fuck yeah dude, Cbum only won cuz of his Dorito back.

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.
