The J Wal is the combination of a mustache ride, a cleveland steamroller, and then finishing up with a Dirty Sanchez. This is the kinkiest of all sexual acts.
Mike: "Dude, I took Janie home last night and totally gave her a J Wal!!"
While kissing a girl you just met out that night you un-zip YOUR OWN PANTS, grab her hand and put it on your DICK.
1 of 2 things will happen. She'll play with it or she wont. Either way you know whether to move on or go to work on that broad!!!
Guy: kiss kiss (Guy thinks. gotta pull the J-Walsh)
Girl: kiss kiss Guy: un-zzziiippppp. Grabs her hand puts it in his own pants.
Girl: giggle giggle... you don't wear underwear and your dick is sooo big!
Guy: I know.... (Close the Deal!!!!)
