Spamalanche 

The overwhelming number of spam messages that appear when kicked off by clicking on a link.

That link caused a spamalanche of porn sites to pop up during my presentation!

spamalanche 

The avalanche of e-mail that occurs when someone inappropriately sends out an e-mail to a large list, which then triggers "reply all" from many list members to remove them from the list. When this occurs during a holiday, the out-of-office messages also echo back and forth, worsening the problem.

That IT newbie sent a note to a global e-mail list during Christmas, and the ensuing spamalanche crashed our server!

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.

Savalanche 

When Sav busts a load on your face and you fall asleep with it on. Then the next morning you realize it was Sav's jiz on your face, so you leave it on for the rest of the day for the world to see.

Half of Connecticut's female population is currently walkin around with a savalanche.

scatalanche 

A powerful explosion of greasy, runny shit from your ass, such as you might have after eating 10 White Castle hamburgers.

Mikey barely made it home from White Castle, sprinting to the toilet for the scatalanche from hell.
