Nabeshin is the most hilarious comedy character ever invented. Though nobody knows him, he magically shows up, having a full understanding of the situation, and fixes everything. The deus ex machina of every Excel Saga episode, that's our Nabeshin.
Notes: Can be used as an adjective.
"Yeah, so I went to a college and did a Nabeshin in the locker room, saved the day, nobody got hurt."
