Term used in place of what would normally be the word "gay" to describe something repulsively camp, in order to not offend your non camp gayfriends.
Dude your Hawaiian shirt reeks of fabulousness! Now quit flapping your arms all over the place on the way back from the bar. You'll spill your Bacardi Breezer!
Commonly overused word by fake, obnoxious, insecure type girls who feel the need to insincerely flatter people and try to make all of their mundane moments seem extraordinary hoping to manipulate people.
When applying makeup, it can be either done to extreme fabulousness or toned down to a more natural fabulous, with your standard, non-makeup covered face filling in the blanks.
See? You've now been made fabulous!~
It's not called looking gay, it's called looking FABULOUS!
