This can only happen when a white male is going inside the brown eye of a japanese female. Right as the male is about to cum, he drives his elbows into the female's back (thus making a cracking noise). The male is then the japanese cracker, making the female the japanese crackee. Sometimes as a bonus, the male can also cum on the japanese crackee's back, which makes a nice little reminder of the night's events for the woman.
"Oh man, I was a total Japanese Cracker last night!" Bob

"Did you cum on her back? Only real men can get away with that." George

"I always do! It was EVERYWHERE!" Bob
