PSP Porn
Currently there are around 2,000 people a day searching for PSP Porn, according to the statistics on overture. Thats a lot of people looking for the PSP being used in non-standard ways.
Unless they are looking for porn to play on the PSP, rather than just rude pictures of the PSP, in which case it perhaps makes a little more sense, if not entirely a clean concept. And why do so many people want to look at porn on the PSP anyway, its hardly the thing to show your boss at work, or the old woman on the bus sitting next to you.
Oh, and if you came here looking for some PSP Porn, sorry, there is none. Try FHM or Nuts if you want to see some rude laydeez.
