creepy uncle vibe

That sense you have when a guy both looks and behaves like a slimeball who could be your creepy uncle who once couldn’t stop smelling or touching your hair or making endless comments about your “figure.”

Yeah, he’s definitely got that creepy uncle vibe; I’m not sure if it’s the greased-back remaining hair or the furtive glances, but taken as a whole, it’s something I most certainly want to avoid!

Uncle Al Sober

One who has quit most mind and mood altering substances after years as an absolute drug fiend! With the notable exception of weed, beer, and shrooms. Named after the sobriety combo of legendary frontman of Ministry himself Al Jourgensen.

Person 1: I thought Island was sober, but he's totally tripping balls on shrooms?

Person 2: He is, he's Uncle Al Sober. Quit all the hard stuff besides weed, beer, and shrooms just like Al Jorgensen.

Person 1: Ahhhh, well as long as he ain't shooting dope into his pee hole again.
