When a girl is giving you the best head you've ever received and you just know she's going to not only let you come in your mouth but swallow the entire load while gazing lovingly/lustfully in your eyes but then she pulls you out and slaps you as hard as she can on your balls. You then start crying like a bitch and she posts it on Youtube. The name derives from some dude named Wally who didn't get head often but whenever he did this happenedd to him, coincidentally.
Damn I was just bust the biggest nut of my life when the hoe gave me a Wallypalooza!!!
