A girl you relate to as if she's your girlfriend but you aren't having sex with. Can be a friend's girlfriend, a close friend, a roommate, etc. Often results in sex. Sometimes you deny each other sex since its immoral or taboo (c.f. friend's girlfriend "no sex girlfriend"). Other times it's just because one of you isn't into the other or it's mutually platonic but just kind of creepy how much you act like you're banging. Can be abbreviated using the acronym NSGF.

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.
