look up any word, like bukkake:
When you walk into the women's restroom to a stall and find urine or poop with period blood in the toilet unflushed.
Person #1: Ewww! Theres a Chile Surprise in this stall!

Person #2:Hey, she walked into a chile surprise! Haha.

Person #3: Its always funny when it happens to someone else.
