We all know there's no greater way to measure sass than passive-aggressive notes left for your neighbours, but this lengthy rant - oddly poetic in its own way - takes it to the next level.
The furious full-page message was left by a tenant who was kept up by their noisy neighbours, but this excellent description of the whole thing sounds like a scene out of an American high school movie.
The angry tenant gives them the Laguna Beach-esque names Kristin, Becky, Chad, Jen, Tracy and Megan - and proceeds to dish out the insults.
"Being loud in your own apartment is one thing, but letting Becky stumble around slur-yelling in the hallway at 3.30am is another," the note reads.
"I understand Kristin is excited about her new stewardess job at Air Canada, but she needs to tone it the f*** down because your neighbours are trying to sleep... and we all know WestJet is better anyway."
