May 15 Word of the Day
A few weeks ago, no one had β€œcheugy” in their vocabulary . Now everything is saturated with the word. It’s in our heads. It’s in our homes. Everyone is asking: β€œAm 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 β€œI LOVE The Office!” from all her dating profiles. She’s unrecognizable.
