catavalanche 

When a soundly sleeping cat suddenly falls off the top of a sofa or other piece of furniture.

We saw our sleeping cat slip down the front of the sofa in a catavalanche.

The Catavalanche 

The act of a man lifting up his large, floppy abdominal pannus before receiving fellatio. Immediately after coitus he releases the sweaty mound and it collapses onto the face of the unsuspecting female while she is still attached to his flaccid member.

Jackie was always a fan of hookin up with the big fellas... until Ron decided to crush her face with the catavalanche.

chavalanche 

The immediate period after Townie pubs and clubs kick out at the Weekend when hundreds of chavs fall out of the establishment to fight, copulate and inbreed.

Police officer 1: Well Lenny I think we're going to have a right chavalanche on our hands tonight when Evolution kicks out!

Police officer 2: Lets hope so Dave I cant wait to take out a few of those grubby little Pikey Fuckers.

Even though your daddy just lost 12 million, random large sums of money fall on you from the sky.

That Chris got hit by a serious cashvalanche last month. I hope he's ok.

catalanche 

When 2 or more cats run down a flight of stairs, causing a rumbling sound and knocking over everything in their path. This often due to excitement and/or food.

"What happened to you, James? You look like you got in a fight."

"No, no...I just got caught in a catalanche and was swept down the stairs."
