May 15 Word of the Day
A few weeks ago, no one had “cheugy” in their vocabulary . Now everything is saturated with the word. It’s in our heads. It’s in our homes. Everyone is asking: “Am I cheugy? Am I a basic ass bitch? Am I GUILTY of being cheugy?”

The proliferation of cheugy in the mainstream discourse can only be attributed to one source: mental terror. It’s an orchestrated psychological trap to make you question your tastes and interests in the eyes of others.

You are not a cheug. YOU’RE PERFECT!!!!

It is very suspicious that the cheugy mascot is a Minion, a literal cyclops, a deformed
yellow panopticon in overalls ... do not let the all-seeing eye to control you. Be vigilant. Resist cheugy psyops.
Becca is another victim of cheugy psyops. I saw the garbage truck take all her Ugg boots yesterday. She even removed “I LOVE The Office!” from all her dating profiles. She’s unrecognizable.

Big Montana is a derogatory term in regards to when a girl who is a whore has so much vaginal penetration and wear n' tear, that she has vaginal folds that make her box look like an Arby's Big Montana sandwich.

The abbreviation "BM" means the same thing, but is normally used in order to get some strange at the bar or get a drunk chick to show you her vagina.
Example 1: "Fellas, that whore I hooked up with last night looked like she could have been a model for Arby's. All she had to do is spread her legs and show you her Big Montana and boom, she would have been the pinup for a #4 on the Arby's menu board."

Example 2: "Show me your fucking "BM" you cum drenched whore!"
