back wash is when someone drinks out of a bottle or container that more than one person is drinking from and pour some of the beverage from their mouth back in, or the worst part Saliva/spit, or really be both. thats why everyone needs to pour their own glass. and dont let your kids drink out the juice jug. can cause hiv and aids if someone is infected. etc anything like that.

when your penis is washed either by the wetness of a girl's mouth or by the wetness of the girls vagina. Also, may be used as a wager in a friendly bet.
I'm so glad I'm hanging out with Shirley tonight because I know I will get my pean washed.
Dude, that girl is such a slut I know I can get my pean washed tonight.
I'll bet you a pean wash that you can't fuck that girl tonight.

a sexual position created and made famous by pornstar Tony Eveready. It involves the female laying on her back while vertically projecting her vagina and anus. Then placing both male testicules in the gaping asshole (post anal coitus) and "flipping" the penis to insert it into the vagina effectively creating an epic double-penetration maneuver while requiring only one male. When Tony was looking to add some spice to his love life he decided to "freak his bitch out" by filling up her "snug asshole" with his "nuts". He was later heard saying "I'm goin' wash your dog..." and dog-washing was created.
After a particularly hard day at work, Bob couldn't wait to engage in some dog-washing with his wife.
