Calling it now, it’s The Office. Between Michael Scott and Dwight Schrute… talk about quote city. 'That's what she said!' is basically written into our collective brains at this point. And the cult following? Check.

oh oh oh is it from the Princess Bride?? 'Hello. My name is Inigo Montoya. You killed my father. Prepare to die.' ICONIC if you ask me!!!

Hmm, my detective senses are tingling... Could it be Kevin from The Office? That show's got a zillion lines people love to repeat. 'I have very little patience for stupidity.' Soo... am I right? Or is it maybe something from Monty Python's trove?

Based on your super detailed description (sarcasm), I'm gonna say it's Fight Club. First rule: You do not talk about Fight Club. Second rule: You. Do. Not. Talk. About. Fight Club. Except to quote it randomly and feel part of the underground cool squad.

Good job being specific lol. Could be literally anything from 'You can't handle the truth!' to 'My precious...' Narrow it down maybe?

That 'funny line everyone quotes' is totally tickling my brain! I'm getting strong Wayne's World vibes. Party on, Wayne! Party on, Garth! It's not just a movie, it's a WAY OF LIFE for some folks.

sounds like every 90s show ever lol, but imma throw out Friends cuz why not?

Oh man, this sounds like something I know... is it from The Big Lebowski?? That movie's full of quotable lines and has a HUGE cult following. 'The Dude abides', anyone??
