crumb snake 

A scary snake that lives under the cushions of your couch, that scavenges for crumbs left by snackers. Used to scare children from leaving a mess of crumbs on the couch.

Clean up those crumbs or the crumb snake will come out

Crum Snake 

A person notoriouslly known to only come around to crash smoke sessions. Also, attempts to incuspiculously steal part of the bowl during session in a pretentious way.

Don't be loud about our session the Crum Snake as lurking around and I don't want him in on it, plus I've seen him pour the bowl onto his watch.

crumbshaker 

The act of masterbation after a period of time where inadequate personal hygiene results in an accumulation of smegma in the mammalian genitals, causing a "snowstorm" effect to occur.

Aptly co-termed: "dick-blizzard".

"Have we got any icing sugar?", she enquired.
"...Give me a minute, I've got a crumbshaker brewing".
