1.
A genre of rock music performed by women. See also
A tongue-in-cheek term coined by Thurston Moore of the band Sonic Youth in the early-1990s to describe the female or female-fronted rock bands achieving a modicum of success at that time. (L7, Hole, Babes in Toyland, etc.) Stated in jest, it still managed to anger quite a few women, who felt that it demeaned their struggle against the misogyny entrenched in the music scene.
They should do a foxcore Lollapalooza tour- it'd be like the Lilith Fair, but rock oriented.
