Havalanche 

Having so much of something that it can or does collapse on you at any second. It can also be a situation where the amount of something to accomplish is so high it takes or is going to take you an uncertain amount of time to handle.

Can be actual objects or a situation

The movers stacked all our stuff so high when they untied the rope a havalanche fell on top of me.

I'd love to meet up today, but there's a havalanche of client phone calls I need to handle and I have no clue when I'll get done.

Party Avalanche

When you haven't been to parties for a while due to excessive studying/work.

Finally, you go to a party but it triggers the urge to party ALL THE TIME. Usually subsists after a week.

Student: Have to study hard. Gonna get that Ph.D.
Dude: You're going to Jenn's party tonight.
Student: OK. I suppose it won't kill me.

-1 week later-

Student: YEA PARTY AVALANCHE! I haven't been home for a week! This rounds on me!

Penis Avalanche 

The result of a crappy band name maker, Penis Avalanche is the name of the dopest jazz band in the northern hemisphere. Playing hit singles such as "Trunk of the Pussy Spray" and "Fuck Mel Gibson" the band has quickly gained success as the number one band in Albion, Washington.
The band has since broken up, and reformed so often, that most of the members have no longer play an instrument and instead stare awkwardly at each other for the better part of 12 hours while watching hipster music videos on Youtube and making fun of their poor bass player.

"I can't wait to see the Penis Avalanche, I heard they've reformed again!"

Swiss Avalanche 

When a man stands behind a bald person on their knees and slowly cums on the top of their head so it will run down the persons face, like an avalanche runs down a mountain.

“Man, I want to Swiss Avalanche on Amber Rose so bad.”

Wife: “Honey, the results are back. I have Cancer. Now, we can finally Swiss Avalanche like we’ve always wanted to.”
