What is a "weasel"?

The weasel is a small, slender mammal known for its agile and ferocious nature. It belongs to the Mustelidae family, which also includes other animals such as ferrets, badgers, and otters. Weasels have a long, slender body with short legs and a small head. They are typically brown or reddish-brown in color with a white or yellowish belly. Weasels are known for their hunting abilities and are voracious predators, feeding on a wide range of small animals, such as mice, voles, rabbits, and birds. They have sharp teeth and strong jaws, which they use to catch and kill their prey.

"Weasel" is a slang term for a person who is sneaky, untrustworthy, or likely to betray others.

The term is used in informal, critical, or mocking contexts to describe deceitful or underhanded behavior. It is derogatory, context-dependent, and not vulgar, signaling distrust or contempt rather than sexual or extreme offense.
