The term given to an imaginary aura surrounding a person after commencing a certain action, saying a certain word or phrase, or attending a place. It is said that one is "covered in Gayness" when they do something, which in turn makes them look gay, sound gay, or ultimately be gay.

"Dude, you just touched my dick with your hand. It fully just brushed by it and i felt it on my knob, slightly."
*John proceeds to slide his hands down his chest, to his stomach and over his thighs, in a brushing action*
"I know, I'm wiping off the Gayness as we speak. I feel so gay."

"Did you just say mint? and banging?"
