snovalanche 

Deconstruction: 'snot avalanche'.

This is the sudden and unfortunate avalanche-like unleashing of snot as a result of sneezing.

This often happens when you are in a situation where resources to combat said snovalanche are unavailable, i.e in a lecture, meeting, religious service, and so on. Very embarrassing.

Friend: 'Hey, why did you run out of the lecture hall with your hands covering your face earlier? Ha, everyone thought you were crying at that video.'

You: 'What, they did?! Ah, I had sneezed, but it was a snovalanche, and I didn't have any tissues.'

Friend: 'Oh. Nice. Maybe it's best that they thought you were crying.'

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.

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.

snavalanche 

A large amount of snot that comes out of your nose and gets all over your face/clothes/innocent bystanders when you sneeze.

1.) Man, this cold gave me a snavalanche so bad I had to change my clothes.

2.) Don't bring that cat near me unless you want to see a monster snavalanche!
