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.
