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!"

All Availability Rule 

Regardless of their own status, men are fundamentally averse to encouraging a relationship between any woman and any other man.

Girl: "I love what you and Jane have together. I want that. I should say yes to Jim."
Guy: "No you shouldn't. He's a jerk. I hear he has done time and is $200k in debt."

Girl walks away dejected

Guy 2: "Why did you do that?"
Guy: "All Availability Rule. Never know when I may need her single"
