A weasel is a furry little rodent, who tends to be cute and murder birds, like chicken: 2 in 1
Very agile and mobile creature, who can slip through tight spots and eat your eggs, if you aren't watching.

Weasel can also be a description for someone clever or menacing.

Some cartoon or game characters are weasels, where they have sly, slim, clever and sneaky behaviors and they have a nice smirk or a grin on their face. Unlike the real life counterparts, they usually don't eat eggs nor murder birds in cartoons though for some fucked up reason.
After 'someone' stole my eggs from the fridge I yelled out: "The weasel stole the eggs, what I just mugged from someone!"
When someone rips or pulls you off, you probably would think: "What a weasel!"

A small rodent like person who is renowned for his sneaky, dishonest and generally unpleasant nature and is universally disliked. The weasel often has dirty gingery hair on his face and snout and is found skulking around in the shadows in a manner very consistent with other rodents.
