This takes place when you are enjoying felatio from your lover on the 2nd story or higher in a building. You pull out at money time, and fire a frozen rope of dick snot into her face, temporarily blinding her. At this time, your partner would be further incapacitated, so you could utilize this opportunity to smash a taco in her face, either hard or soft shell. (soft shell is suggested for long term relationships, hard shell for one-nighters). At that time, you inform her you'll walk her to the bathroom to clean up, at which point you throw her down the stairs and yell "Avalanche Amigos!!!"
Beatrice was being a bit of a pain in the butt yesterday, so after we came home from the bar and taco bell, I gave her a Mexican Avalanche. She should be back at work by next Thursday.
