I thought it would be obvious what was meant, but since I apparently again overestimated people's intelligence I have now clarified so it reads "Buffy the Vampire Slayer"/"Angel the Series" Femslash.

Maybe I should make it "Fictional accounts centering on or prominently containing non-heterosexual romantic and/or sexual relationships between two or more characters from one or more of the TV series 'Buffy the Vampire Slayer' and 'Angel the Series'"?
