If there's one thing that's a sign of a forward-thinking person, it's a tattoo. Even more so are tattoos in Asian writing because, you know, that sh*t's profound n' sh*t. Confucius was Asian! (I wonder if Asians get tattoos of stuff in English on them, you know, because Shakespeare!)
This dude-sandwich of dudes, who are obviously not gay, but just a close-knit bunch of dudes who felt strongly enough to be bound by mutual Asian profundity, clearly know a gangsta tattoo when they see one. Don't tell them that it really means totally not gay paleface partner of hard buddy team.
