Territorial Pissing Syndrome.
Named for the Nirvana song Territorial Pissings in reference to the line 'just because you're paranoid, don't mean they're not after you'
Charatarized by a full-blown case of paranoia with a slight possibility that someone might actually be out to get you.
Me: ...so i concluded that Major League Baseball was reading my 'bad thoughts' via satellite feed, from the microchip the aliens implanted in my neck!

Psychiatrist: Very interesting. A few miligrams haloperidol daily should cure that up. Has anything else been troubling you recently?

Me: Well, I'm pretty sure the religious nut next door is going through my trash trying to find evidence of satanic rituals and gauging my drinking habbits. And, recently, I've seen him stockpiling lighterfluid daily with his pick-up. At this point, I suspect he's planning on burning my house down with me in it.

Psychiatrist: Well, it's not entirely impossible, especially since you have 'Infant Sacrifice, Lord Beelzubub' tattooed on the back of your bald head. However, since you're a complete wackjob, I'm penciling it into your case file under TPS and uping you meds.

Me: Oh cool.

TP when used on most forums usually stands for "Top Poster" Top posters are anyone that has been on the forums for a long time, and have nothing better to do with their life. They sit around all day posting new mindless threads, acting like they are all good friends with other TP's just to become more popular. If anyone else posts on their threads, they do nothing, but talk shit on them, with out even caring what they've said. TP's only like TP's, and nobody else. They then sit at home and do nothing, but worry about stupid HS shit, and waste their life by trying to see who is the hottest top poster, or asking what top poster has fucked what top poster. TP's are usually really big on the site www.plurlife.com
You shouldn't post on any threads the TP's are a bunch of trolls & grammer natzis!!

Hey, I post on the forums, those people are my friends.

Do you even know any of those people in real life?

No, but they totally think I'm the hottest TP on plurlife, I would fuck all of them for voting for me.

Tiny Penis Syndrome. Causes the affected person to act arrogent and most likely have a very large truck and/or lots of expensive stuff
Did you see James trying to be all cool and and impress everyone with his truck's new stereo system? He's probably compensating for his bad case of TPS.
