When you devour a box of Doritos Locos Tacos and don't lick your fingers. Then you finger pop your girlfriends recently contaminated butt hole (She has to have just pinched a loaf).
Tim: Man, after I was finished the 12 pack taco box from Taco Bell, I then threw my hand down my slam-piece's pants and got my cheesy fingers in her recently packed asshole.

Dave: Wait, are trying to tell me you Zesty Taco Finger Popped her?
