A girl kiss meme is video footage of females kissing, usually between inebriated heterosexuals in a party setting. These videos are not to be confused with pornographic marketing material or other movies featuring actresses kissing.
Often, the person filming will dare two girls to kiss, and what starts out as a joke gesture can very quickly turn into an unexpected (but brief) foray into lesbianism.
The origin of this meme lies in the more unruly side of American college culture (and especially Spring Break culture) in which binge drinking, women showing their breasts to crowds, and women kissing each other are periodically video taped and photographed. The Girls Gone Wild franchise has exploited this phenomenon, inspiring many individuals to both perform for the camera and to make videos of their own.
Pat yourself on the back if you ever find yourself at a party where a girl kiss occurs. If you happen to have a video camera... well, you'll know what to do.
