Also known as "muddy underoos."
This is a phrase used to describe when a female's undergarments are exposed, and the viewer can clearly see splotches of fecal matter.
This even is most commonly associated with fat whores and white women named "Lindsay" (i.e., Lindsay Lohan).
Panties adorned with cupcakes are worth bonus points, and are dubbed "chocolate cupcakes."
Person A: "I heard that on the set of Lindsay Lohan's new movie, she vomited all over herself, and then passed out on the floor with her fanny in the air!"
Person B: "Yeah, I heard! Everyone was able to see Lindsay's cupcakes!"
<Person A vomits>
