What if ubislop made butt creed because china wanted to poke the nips

Not the correct way to do it.

The correct way to antagonize the Japs is not with a Black samurai.

But with a Gook Samurai.

There have been literal minor samurai battles because a Jap Daimyo arranged marriages between a Gook retainer and a Jap foid.

Japs get real annoyed if you remind them that Kyokushin Karate - aka the manliest form of Karate, where belt promotions are earned by having the entire dojo batter the piss out of you - was created by a Gook who went around beating up Burger Military Police, killing oxen and dojo-smashing Japs.
