This unique maneuver happens when one male adds a hefty amount of "tex mex" spice onto the shaft of his genitalia. This male would then proceed to penetrate a male/female rectal sphincter and thrust rather violently to marinade the anal cavity of the recipient. The receiver's asshole will feel like it is on fire or better yet, feel as if a dozen firecrackers are going off inside of them. If necessary the male may choose to extinguish these "flames" or "explosions" by ejaculating into the anus, or you may leave the recipient in an excessive amount of discomfort.
I came home from work one evening and my bitch didn't have supper ready, so i gave her a Spanish firecracker and that learned her.
