Abra Host

To say that one is going to throw a big party in order to receive positive attention from ones peers, before canceling the event last minute. Often followed by a large backlash from the disappointed would-be party goers.

Chad 1: "Dude, are you going to Eugene's party this Friday? I heard it's gonna be insane!"
Chad 2: "Eugene? This is like the 5th time he says he's going to throw a party, I guarantee he's pulling yet another Abra Host"
Chad 1: "Wow, really? What a douche."
