When you titty fuck a girl with a juicy ass, so that your butt slides all over her belly.
Billie had Taco Bell for dinner, so his usual nightly titty fuck session with his girlfriend during Letterman turned into a Cincinnati slider.

Binge eating White Castle Sliders almost to the point of anal prolapse and going out and writing your name in poop in the snow.
Writing in cursive is much easier when pulling a Cincinnati Slider if you don't have the sphincter control.
