I think I finally pieced together what the fuck's going on here. Basically, it's these two gay muscle-porn stars, who were in a jockstrap-wrestling video that's popular fodder for a japanese video-editing site similar to Youtube Poop, where their dicks are always covered by a baby face for some reason, and the chick is Rin, she drives a steamroller, they're in an Initial D race, and...
Y'know what? Fuck it. I can just summarize the whole thing by saying "It's Japan."
