what fergie says her being promiscuous is, because she blows kisses that puts them boys on rock rock, and they be lining down the block just to watch what she's got.
"But, I ain't promiscuous and if you were suspicious, all that shit is fictious" - Fergalicious by Fergie

Making up stories about your life and truly believing them, whether to make yourself seem cooler, or to over-compensate for not being the person you want to be.
A state of delusion.
"Are we supposed to believe all these sexual adventures Sam keeps telling us he's done? I think he might be falling into fictionocity."
