A sexual act which begins with the doggy style position. The male is to insert a wad of smokeless tobacco i.e. Skoal, Big Red, etc. With the curvature that the female forms during this sexual act the male then begins to spit on her back. Once a small pool has formed, he then dips his thumb into said pool of tobacco spit, and shoves it up her ass.
Dude, did you jalepeno popper that random chick last night?
Cooking with jalepeños and not getting all the juice off your hands, then later that night fingering a woman. It makes her curl up in a ball and just want to die. It's basically like setting her vagina on fire.
John: Dude, last night I accidentally gave Emma a jalepeño popper.
Justin: Oh man, no way! Did she cry? That must have burned so bad!
