"exwhore" aka "x-whore" aka "exclusive whore" comes from the binary function x-or (exclusive or). There's no meaningful connection beween the "or" and the "whore".

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.

a person who was formally known as a whore but changed their ways. no longer sleeps with everyone

Short for exclusive whore. Somebody who acts like a total whore, but only around certain people.
