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.
An extreme expression for "We're coming for you" or "You better watch your back".
In the movie Saving Silverman, Darrens friend JD shouts, "Comenayeahaw!!".
