I was just watching “Fist of Fury”, a badly dubbed old Bruce Lee film. In one scene, Bruce bursts into a room where the two men who killed his teacher are conspiring. Via the camera, he looks at one man’s nipples and says “So…you’re Japanese!”
Somebody will have to clue me in, cuz I dinna ken this one.
WAG here: I believe much like people think of African American males with big penises, Japanese people are considered to have long nipples. I’ve never seen a Japanese person topless, nor have I seen Japanese porno. I suppose I could do some research online…
The nipply gentleman in question was wearing an undergarment, but nothing of an obvious ethnic origin (at least not to me). The camera was clearly looking at his nipples, as immediately following Lee’s statement, he pulled his undershirt up over them.
Perhaps it’s a coloration issue. I’ve noticed that Asian nipples tend to have different shading than Occidental nipples, so perhaps a slightly different shade would indicate not only Asian, but the general area of Asia where one comes from. (Generally, however, facial structure is more varied and tends to reveal one’s origin quite well.)
