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!"
