Abbreviation of Spencer Pratt and Stephanie Pratt, they of The Hills. Synonym for douche, dickwad, tosser, wanker, twat, bitch, backstabber, valley girl, and all derrogatory terms imaginable.
A neologism based on the abbreviation p.r.a.t.t. for "previously refuted a thousand times", referring to any claim that has been previously debunked, shown to be false, publicly challenged and defeated, or otherwise shown many, many times to be demonstrably and verifiably wrong... and yet continues as a claim by believers in pratt.
What, you still think aliens make crop circles? The dudes who invented crop circles went on TV and showed how they did it! It's like some kind of folk art form. That crop circle alien stuff is all just pratt, man. Move on.
