Background
This song is based on and was created at the height of the "Gekioko Punpun Maru" trend. The phrase, or buzzword, was a neologism that gained popularity in early 2013, created by Japanese Gyaru as a way of expressing various stages of anger using a minimal number of characters. This phrase quickly took off on Japanese social media, especially on Twitter.

"Geki oko" is a Gyaru term meaning "very angry". "Punpun" is an onomatopoeia of expressing anger, such as steam coming off of one's head. "Maru" is a suffix for formatting terms to classical names.
