'Suppressive Person' as coined by self-proclaimed Scientologist, Tom Cruise in the ever increasingly popular interview seen on youtube where he can not control his laughter and brags about stopping to help people who are in accidents along the highway.
"They said: 'so, like... have you met an SP?'" <cackling laughs> "And I looked at them and...You know..."
"And I thought how what a beautiful thing because maybe one day it will be like that. You know what I'm saying? Maybe one day it will be that..." <can't control his laughs> "Wow, SPs, like, they'll just read about those in the history books, you know." --Tom Cruise

A ramp tramp, aka a Skate Park Slut. Slutty girls that hang out around skate parks for any reason other than riding a skateboard. SPS want to ride skaters rather than skateboards.
I can't shred ssbsts when those sps are here.

Why do sps always show up when I'm trying to skate?

That sps over there wants you to session under the ramp with her.

SPS are easy to spot. They are always at the skate park, but never skate.
