A young, newbie, male "raver". These types may not be scantily clad, but exhibit the personality traits of the female equivalent, the prostitot. Prostibros are usually younger in age and can be identified easily. They will usually be wearing a facial bandanna indoors, brand new over priced sneakers at an old school party, basketball shorts, shutter shades, neon tank top/overly tight tee shirt worn to show off "guns", or some sort of clothing referencing "Molly".

The prostibro enjoys edm, mainly dubstep and trap, and will attempt to shuffle no matter the style of music.
The prostibro was excited because he has just gotten his new light up tshirt in the mail and was ready to show it off at the dubstep concert that evening.
