Okay, some Japanese and anime trivia:

"God in highschool"/"Kami-sama de chuugakusei" is from the anime http://en.wikipedia.org/wiki/Kamichu
Not very related to >>137 because in "Kamichu" the god is a schoolgirl and BOKU refers to oneself as male.
The only link is "kami-sama".
Note that -SAMA indicates reverence, and that BOKU is a boasting or childish "I". Therefore "BOKU WA KAMI-SAMA" is showing that the speaker is not proficient in the language and/or quite vain.
