look up any word, like fuck boy:
1. The level of blondeness accomplished by an overdyed, shopping-obsessed boy-watcher; male or female
2.The level of preppiness acquired by an object or other non-person
3. The temporary state of preppiness, usually by a normally non-prep person
1. OMG, that bra-stuffing twit's preposity is off the charts...
2. That tie is just oozing preposity...it clashes with the wristband
3. After Lindsay's brief fit of preposity, we had to quarantine her..in case it spread.
