One of the most offensive Japanese slang terms which essentially means to rape a man in a prison and then excrete all over his body. This method of violence is also used by gangs outside of prisons as well and by many teens trying to cause offense to others.
Boku wa anata de ichiichi!

Translated as "I will ichiichi on you!"
