Upside Down syndrome

The disorder in which a person's Down syndrome is so severe that his face is completely rotated out of proportion. More severe cases can affect muscle girth, especially in the forearms. This renders the victim's forearms indistingiushable from pencils. One's speech may also become unamusing and trite.

Chris Max, what's up with your face?
Max BABABABAABaabaaba!!!
Chris O, you must have Upside Down syndrome, which renders yours forearms indistingiushable from pencils. My bad.

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: Hey Zach how was your date with Pam last night?
Zach: Oh it was great. Did you know she's Korean?
Josh: No way did she tell you?
Zach: Well I pretty much figured it out when she gave me an upside down chinatown.
Josh: Haha score bro!

Upside down Riverboat

This is a sexual act that is similar to the "69". The female participant is on top and holds her arms straight while servicing the gentlemen on the bottom. The male holds the females feet in his hands and rotates the ladies feet in a circular motion to resemble the propeller on 1850's riverboats.

David Wilcox's "Riverboat Fantasy" must be playing for the entire duration of the Upside down Riverboat.

This sexual position was inspired Cowboy's and Alien's which features an upside down riverboat.

So then we Upside down Riverboated all night.
