upside down chinatown

A sexual act originating from the Shang Dynasty in China. The upside down chinatown consists of an asian female filling her snatch with rice and soy sauce and laying backwards to her partner. Her partner then proceeds to eat out her filled vag. The act originally was intended to be performed between two asians but over time it has transcended into modern culture, including spinoffs like using chopsticks and incorporating other ingredients like sweet and sour pork.

Josh: No way did she tell you?
Zach: Well I pretty much figured it out when she gave me an upside down chinatown.
