upside down monkey sex 

One partner hangs upside down from a high place, while the other partner runs around the room and beats their chest while shrieking at the top of their lungs. Once out of breath the hanging partner must fall down on top of the other partner's back and they must wrestle to figure out who is the dominant one.

"Hey fellas, see that girl over there? She is into all kinda of weird stuff, even upside down monkey sex!"

Upside Down Mouth Pound 

When you lean a girls head off the end of the bed in order to open up her esophagus and you furiously enter and exit your penis.

Kelly: "So Rachel, did you finally give Jerry a blowjob?"
Rachel: "Blowjobs are for the weak, Rachel. I let Jerry do the Upside Down Mouth Pound on me."
Kelly: "That seems like it would hurt!"
Rachel: "It's not that bad since it opens up my esophagus."

upside-down margarita

A way of preparing a margarita where someone sits in a chair with their head held back and their mouth wide open. Someone else then pours in their mouth a shot of margarita mix followed by a shot of tequilla a little more mix. When finished, the one who received the drink leans forward, shakes their head to mix the ingredients and drinks it in one gulp.

Sit over here I'll give you an upside-down margarita!
