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

I'm so glad I'm hanging out with Shirley tonight because I know I will get my pean washed.
Dude, that

I'll
bet you a pean wash that you can't fuck that
girl tonight.
