An alternativespelling of 'Fat' that is often used in some game console communities on the Internet to destinguish Larger, or Phat, versions of a particular console from more Compact, or Slim, versions of the same console.
I sold my Phat PSP 1000 and just bought a Slim PSP 3000. Man, it runs so much smoother, though it's coniderably harder to flash.
Adjective: A word that grotesquely large people use to describe themselves so they feel clever, witty, and funnier than that of one who is at an envied weight.
"GOD DAMN! You are one PHAT lard."
"You said it, baby! I'm BACONLICIOUS!"
