The erotic act of stuffing a woman's panties in her mouth, vagina, or ass. This is a form of foreplay that looks increadibly sexy, especially when the panties (normally a dark thong) are removed, tasted, and inserted into her pussy and/or ass, then stuffed back into her mouth for tasting again. This is normally depicted in hardcore european pornography in features where porn starlets wear alluring lingerie and show it off heavily in the pre-sex of the scene.
You: That girl working in the Hollister over there is too fine!!!
Me: The blonde? Two weeks ago I took that stuck-up bitch to get some eats at a swank little place downtown and she didn't even offer to pay her half of the bill. So, I took her to the bathroom and gave her twat and dirty little mouth a panty stuffing for dessert.

Dude, you should have seen what I did to that chick last night. We were panty stuffing so hard that when I pulled them back out, they were wetter than when they come out of a washing machine.
