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.

Slap upside the face

The polar opposite of getting slapped upside the head. A person will take their hand like the are about to slap someone but push the person's chin up an smush their hand in their face. New fad that originated January 7th 2012 created by two siblings in Walmart

Because of the way the face is pushed when this occurs it results in the embarrassment of the person slapped an a moment of silence

Toni: shut up derek before I slap you upside the face

Derek: okay okay dude I will stop

Tina: I shall slap upside the face of yours for being a turd

Gina : sorry please don't do that

Upside down triangle

Someone whose upper body is larger and not in proportion to their lower half. May occur in someone with broad shoulders, or who is overweight.

Her incredibly broad shoulders and slim waist make her look like an upside down triangle.
