Crumb shark 

A pet, most often a dog, but possibly a cat, bird, ferret etc, who follows you into the kitchen or when you’re eating hoping that you will drop scraps of food that they can eat.

Every time I make breakfast my crumb shark of a dog stands between me and the stove hoping I drop some food.

crumb sharking 

When your pet, usually a dog but not limited to dogs, follows you around to areas with food (kitchen, dinner table etc.) in hopes that a scrap of food will be dropped for their consumption.

Every time I’m in the kitchen, that dog follows me in crumb sharking around hoping for a treat.

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".
