kaishaku
The guy who finishes the job when the samurai is too busy being dramatic. He’s like the guy who comes in and says, 'Just kill him already.'
The samurai did his fancy incision, but the kaishaku came in and said, 'You’re going to die anyway, so let me do it fast.'
During the seppuku ritual, the kaishaku got impatient and just cut the guy’s head off before he could finish his speech.
My kaishaku was so impatient, he beheaded the guy before the incision even finished.
