A short way of explaining a very long and complicated process that requires lots of work and energy, similar to that of a crazy occult ritual.

Literal meaning: Samurai ritual self disembowelment over the ass of C'thulu the Lord of Darkness.
seppuku Cthulu

Friend: Want to hang out later?
Me: No, my computer is broken and I have to commit seppuku over C'thulu ass to fix it.

Cthuluism 

The religion based on the person and teachings of Cthulhu

Cthulhu is a fictional cosmic entity created by writer H. P. Lovecraft and first introduced in the short story "The Call of Cthulhu".

Cthulhu also has a cult-like following in the real world. Some even believes Cthulhu is the worlds real savior, believing one day Cthulhu will reawaken and will Kill most of the Earths population leaving the cultist and believers

I believe in the religion of Cthuluism, and one day the elder god Cthulhu will return.
