Phildoubt
That feeling you get when your loser friend says he is gonna hang out with the boys, but never does. You give him a sweet nickname (Phildo), include him on text threads, and even are friends with him on Facebook. Still, he disappoints. Phildo + doubt = Phildoubt.
Sonny: Hey Roger, is Phildo gonna hang out with the boys this weekend?
Roger: He said he is, but I Phildoubt it.
Roger: He said he is, but I Phildoubt it.
