Sepuku 

A ritual suicide practiced by samurai in Japan, usually because he has brought shame and dishonor to himself. This might have resulted from failing to protect his master, or otherwise breaking the code of bushido, "the way of the warrior". The soon-to-be-deceased kneels with a short sword in both hands, and disembowels himself. Immediately after this, the sepuku assisant, known as the kaishakunin or "second", beheads the person with a sword. The ritual goes into great detail about washing and dressing, last words, etc.

The disgraced samurai was asked to commit sepuku by his superiors.

Sepuku 

A misspelling of "Seppuku," particularly common among people with low IQs.

I committed sepuku because I think "Seppuku" is actually spelled "Sepuku." Also, possum tastes great and I wear pants on my head.

Beard Seppuku

When a man attempts to trim up or style his beard and makes a fatal error, forcing him to go clean shaven rather than bear the shame of failure.

Seppuku is the custom of Japanese samurai to commit ritual suicide upon suffering great dishonor or failure.

Pierre: "Hey dude, why'd you go clean shaven?"
Antoine: "Ah.. well, I made a mistake while trimming and had to commit beard seppuku."
