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.

Any of the small creatures that live within the nose. "Boogers" within the nostrils is infact Proboscis Weasel shit. "Snot" in the nose is actually urine from the Proboscis Weasel. They cause no other harm than clogging your nasil passage. You're born with them, you die with them, and they live off of nose hairs that have fallen out.
This damn Proboscis Weasel is giving me so many boogers, it pisses me off!
I've been so busy picking out all the boogers my Proboscis Weasel leaves that I forgot to pick up little Betsy from school.
