Another term for the band Fallout Boy who is currently one of the gayest bands out there. The singer is shit and and the music is basic. Pete Wentz claims a shitload of fame and has become a celebrity off of Fallout Girl for no good reason.
Teeny Bopper: Omigod, I love Fallout Boy, Patrick Stump is so amazing when he sings and Pete Wentz is soooo hot.
Me: Dude, Fallout Girl sucks major ass.

A feminist who thinks that fallout boy should have a girl band and thinks that all boy bands should have a girl version of it.
