When two heterosexual individuals - one an authentic Korean and the other an authentic Chinese, which is male or female is irrelevant - fornicate using the leftover grease from today's breakfast hashbrowns. At the brink of climax, the male will scream "It's hot! It's real hot!"
This signals the female to finish him off by slopping her greased-up fuckhole around his pulsating cock, doing him past orgasm until she also reaches climax - at which point, both will do a synchronized backflip to produce a satisfying *pop* sound when the male slips out of the female, erupting the "secret sauce" all over both participants. If either party misses their landing, and breaks their nose, it is referred to as a 'Korean-Chinese Backflip Tatertot with Ketchup'.
Kim "Hey Wong, can we do a Korean-Chinese Backflip Tatertot together?"
Wong "Oh, of course Kim!"
*After the Korean-Chinese Backflip Tatertot*
Kim "What the fuck?! I didn't order it with Ketchup!"
Wong "I can't breath."
