Sword Boy 

A cute English nickname for the Japanese video game Touken Ranbu, featuring pretty boys as personifications of historical swords.

Are you gonna cosplay as one of those sword boys?

Sword Boy 

The act of yelling "Sword boy!" and then busting a nut on someone's face while they're kneeling in front of you, followed by a swift kick to their chest knocking them to the ground, similar to Arthur in the classic film Army of Darkness.

Man, Ol' Suzy Jenkins won't talk to me no more since I sword boy'd her last weekend, but it was worth it.
