When you maul your partners butthole, furiously eating it out with your tongue. Often the mauling is so intense, their is collateral damage and your chin, nose and, but rarely, eyebrows can become brown

Dirty Armando 

The act of transferring your under arm odor to another person's upper lip, typically via one's index and middle fingers. This results in a recipient who constantly smells your BO. Best accomplished when target is unaware of their fate until it's already too late.

Style points awarded for shouting "dirty armando" while act is in-progress.

After working out together, I thought it'd be funny to give my girlfriend a dirty armando. She didn't laugh.

Dirty Arman

Random man of middle eastern descent, whom enjoys fucking transgender women up the ass and stroking their cock but says it is not gay because they identify as a female. While fucking the transgender woman, he takes a turkey leg, shoves it into his ass, pours hot and creamy KFC gravy down his back, and allows it to trickle into his asshole. He proceeds to wipe the shit off his dick, mixes it with yogurt, and then spreads it on the transgender person's stomach and licks it till it is clean.

Amy - "Did you hang out with Jasmine yesterday?"
Thomas - "Yes I did! We did a Dirty Arman and had me screaming, creamin, and juicin."
