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.
Example:
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!"
