A female, that is younger than the age of 18, who dresses and appears (from a distance) to be an easy girl. When approached closer it becomes evident that they are too young and there would be jail time involved.
Prosti-tots are usually spotted from moving vehicles.
Yo vik! Look at the girl up ahead, she looks soo fine...
(distance becomes shorter)
Damn just another prosti-tot... I'm going to jail for saying that.
