Texas Plunge
When a girl is so loose, that she cannot even be pleasured by fisting anymore. But, by the way of the Texas Plunge. This is when the male takes his head, (the one on his shoulders)lubes it up, and plunges it into the females vagina.
Damn, that chick last night was so loose I had to give her the Texas Plunge.
Texas Butt Plunge
The act of enforcing ones feces in anothers rectum, therefore they may not be able to poop.
My dad gave me a Texas butt plunge last night because I didn't do my homework.
