Condoms. It may sound ridiculous but if you go to a scummy park infested with regular kids, them buying boxes of condoms and throwing them over the park in order to make it look like they've fucked on every ramp is a daily occurrence. It's like they are claiming the spots. the deathbox? you bet. the grindbox? oh baby. The miniramp? roger that. Just today is was cumming (lol geddit) towards the miniramp and my wheels stuck on one of the fucking things (fully rolled out of course)
Also these same kids make up the 'COC' crew, which apparently means Caught on Camera, which firstly doesn't make sense because they were spraying it with their dads car paint behind the halfpipe, where the camera can't see them, and is just plain funny watching this group of boys spray 'COC' on everything. They are now fondly known as the Cock Boys.
Oh, and i shit you not, they did a little piece which looked something like this: 8==========D - YOU 8=D - ME. They really are regular.
