Shavalanche

The act of one's rectum muscles relaxing so completely that feces flows out without any effort or control devastating all in its path like an avalanche.

ohhhh bro after eating that taco I was hit with a series of shavalanches all night long.

I got so pitted I shavalanched my pants.

Mexican Avalanche

To ejaculate in a woman's hair and then throw her down a flight of stairs.

"That chick took the Mexican Avalanche like a pro-skier." or "I Mexican Avalanched her twice and she still came back for more."

Alaskan Avalanche

When you cum on a girls face, slap her with your dick, and push her in a pile of snow

Frosty the Snowman liked to give Alaskan Avalanches to kids when their parents aren't looking

Javalanche

When one has continued to push oneself forward solely on caffeine and then everything catches up to them in a giant, overwhelming crash.

Eli kept herself for up for three days straight on coffee studying for finals, until she just had a javalanche and collapsed crying in the commons.
