Prostatots are the the skinny teens you see running around raves in just pantys an a bra or stickers over their nipples. Some times they wear fluffy leggings and a hola hoop too.
Another adjective might be flufftards, other wise known in the good ol days as kandi kids.
Music festivals are the best place to see prostatots in their natural habitat.
A young girl (around ages 12-13) who is dressing and behaving in such a way that is reminiscent of a prostitute...or her favorite celebutant (e.g. Paris Hilton).
A re-pubescent female who is scantily clad, hanging out in a public area (e.g. the Mall or movie theater) and behaving like a "stupid spoiled whore."
I hate going to the Neshaminy Mall movie theater! It's always way too crowded and always crawling with prostetots! Last time I went some prostetot totally yelled at my boyfriend...she was like 13!
A young girl, usually between 10-14 and commonly 12 or 13, who dresses in revealing clothing. Prostitots are usually young girls who want to be seen as sexy and mature by the older men around them, and therefore end up wearing far too much makeup and dressing in what they think is sexy but simply looks skanky. They usually look like mini prostitutes, which is how the name came about. Prostitots may or may not be interested in sex; some are, and others are simply mistaken about what makes them look grown up and glamorous.
Can also be used as a random, nonsensical insult, though this usage is uncommon.
"Did you see those little girls in all that makeup and those high heels hanging out in the mall?"
