(noun) A term trademarked by Kimora Lee Simmons, one of the most fabulous people in the world. However, anyone fabulous can define "fabulosity" differently. Basically, fabulosity is about being the best at everything, looking fabulously sexy, having the best things, flaunting your fabulousness, and loving yourself and/or other fabulous people around you. Only a select few out of the whole human population are fabulous enough to live in "fabulosity".

This term is most used when someone is peaking in their fabulosity. This term is only used by fabulous people. To elevate the meaning of this phrase, it's possible to add the word "saturated" before fabulosity which means that a person is basking in a concentrated form of fabulosity which is more fabulous than regular fabulousity.
Ex 1.
-"I went to the mall today and got the CUTEST Louis Vuitton purse to match my shoes!"
-"OMG you are totally basking in fabulosity right now"

Ex 2.
-"OMG I just got a new Bentley! It's so shiny!"
-"I wanna ride in it! You must be basking in saturated fabulosity right now!"
