n. The product of a night that starts out at the Mexican buffet and ends up in the last stall of some shithole pub.

adv. To have a case of the Tijuana shitstorms, directly related to low quality deep fried food and excessive hard liquor (or in some cases, piss beer). The victim typically trots like a horse to the bathroom in a panic.
"I never knew chimichangas and Jaegar could produce such a plethora of asstrots all over the back wall of the handicap stall at The Elbow Room."

"There goes Melvin with the asstrots all the way to the shitter! Hope he doesn't blow an O-ring."
