ura omote

"Ura omote" Is internet slang originating from the hatsune miku/wowaka song "Ura-omote lovers". It's literal translation means "One sided" but it is now used to reference the type of male described in the song; a sexual deviant male who uses innocent, virgin, usually younger girls as a kink device, and usually ends up traumatizing the girl.

The song has been translated and listened to in many different ways, but this is derived from one interpretation of the song.

Person A: Omg Matt is such an ura omote... Cassy is heartbroken !!!
Person B: Yeah, he was my first boyfriend. I don't think I'll ever love. I guess it was just sayonara beibe.
