A prostiteen is a teenage girl who dresses scandalously, similar to a prostitute of an older age. They are certainly not as "affectionate" as an actual prostitute, but they dress very similarly.
Be careful not to stare at girls you see walking down the street. Most of the time, they turn out to be prostiteens, and you'll just feel dirty.

An inappropriately dressed teenager, as is the style today. Combination of prostitute and teenager.
Can you believe her mother lets her dress like that? Or do you think she really is a hooker? The fashion industry is turning all these little girls into prostiteens.
