A person within your friendship group who acts like a two-faced little rat the majority of the time, but still manages to stay in said friendship group by the skin of his teeth despite the weasel-like behavior.
Hey, you know that guy that was in the CFNM porno? You know, the one that got sucked by a bloke? He's acting like a right little fuck-weasel again.

A fuckin' weasel. You know the kind. That prick that always ends up ruining your day. That dude that steals your chick. In short, a complete asshole, one that shits all over everything he/she comes near - (team america reference right there). This person is an operator, they appear indecisive and cool at first, however they usually have a behind the scenes motive to fuck your life up.

"Fucking weasel" is an insult that describes someone as sneaky, untrustworthy, or insincere, similar to a "sneaky snake". The term draws from the real weasel's predatory behavior, such as stealing from hen houses, which historically gave the animal a reputation for craftiness and slyness.
