Defecating on a woman's breasts while you straddle her face for fellatio.
Tammy didn't appreciate the Pasadena Mudslide I gave her.

This happens when you leave a windy shit between the breasts of a woman while you straddle her neck for a blowjob. (A close cousin to the Cleveland Steamer.)
Unfortunately this wasn't possible on Ridgly but Baily did well.

Similar to the Cleveland Steamer, but the person doing the shitting has diarrhea. Simply put, 'the mud goes down the mountain.'
Stan ate some Mighty Taco before he gave that chick a Pasadena Mudslide.

The act of leaving a sht stain on a woman's rib cage while having intercourse with her breast, aka "titty fucking."
Seeing how I totally gave her a pasadena mud slide, I don't think she will be calling me back anytime soon.

when one farts while titty fucking a girl, and it leaves a brown smear between her breasts.
When i was titty fucking Sue, she heard me fart, and knew a pasadena mudslide was occuring.
