A phrase that IMHO used to stand for something before the Spice Girls, an all-female band formed by men performing songs written by men, turned it into a marketing slogan. An outgrowth of the Riot Grrl movement, girl power emphasized female empowerment and the active participation of girls in traditionally male arenas. Girls formed garage bands, girls created their own comics, girls published their own zines, girls became involved in political and environmental activism - very much in the DIY spirit of early punk. Nevertheless, it was still very boy-friendly.
