Cover art for Unknown Tongue lyrics by Blue Öyster Cult

According to the NME article, the song "Unknown Tongue" is a true story about a girl that David Roter (co-author of the song) used to know. Apparently a nice Catholic girl, she had a fetish for cutting her big toe with a razor and drinking some of her blood. Of course, in the BOC song, the girl cuts her palm, not her toe.

@Cumaris Wow, I don't think anyone could ever have guessed that....but, BOC does have some very random and unusal meanings in so many of their songs,
