Watty Plunge 

The Watty Plunge refers to Watterson Towers of Illinois State University in which one person climbs to the roof and takes the plunge off the building.

This is a term Illinois State University students use if they are feeling stressed or being a meme.

Student 1: Hey, how’d you do on that exam?
Student 2: Bro, I’m ready to take the Watty Plunge.

Satanic Plunge 

While having sex in the doggystyle position remove penis from the vagina and thrust into the anus. Then, exclaim "WITHIN YOU I PLANT THE SEED OF EVIL" in the most satanic voice possible. See also Bucking Bronco.

Cuban Plunge 

A sex position

As you assume the man-on-top position. Then, she brings her knees to her chest and drapes her legs over his shoulders. Her vagina will be elongated and extended, and his penetration will be deeper and more pleasurable for her. Its a complete win-win situation.

I tried this new sex position last night called the Cuban Plunge.

Oh ya? How was it?

It was amazing! She and I made fireworks all night long.
