Quasadisla (kwas - uh - diz - luh):
A new sexual position in which the woman is compacted as much as possible into a spherical state then wrapped around by the guy as much as possible in the attempt to completely eliminate the light of day from reaching the woman, kind of like the pita of a quesadilla prevents the spicy innards from seeing the light of day. Any open orifice is fair game for insertion. The maneuver works best with small, petite women, especially midgets.
A normal quesadilla, only more delicious because of the name. Often the slang term referring to what your eating while you're hanging out with your friends and you need to laugh at something random.
1: I'm hungry, lets go make some quesadillas!
2: No, I think we should have quesadildos instead.
1: Haha, wth!?
2: Yah, you get the tortillas, I'll get the cheese, and we'll make a big steaming quesadildo
1: LOL
