When a girl throws herself at you, and you don't really have to do any work at all.
aka she's essentially handing over her vag to you on a silver platter. like a sandwich. no, like a vaggieburger...
Danny: Bro, she's legit throwing herself at you. Make a move, she's pretty much handing you a vaggieburger.
Andy: You mean veggieburger?
Danny: No.
Andy: Oh. I get it.
A wedgie is when your undies get all bunched in between your butt cheeks, so therefore, a vagedie is when your undies get bunched up in your vajayjay, or your cookie. Very uncomfortable if i may say so myself...
*some guy goes and gives a girl a frontal wedgie* "OUCH! I have a major vagedgie now!!! It's ridin' way up there!"
