Stitch Cake

A stitch cake is an uncommon event that happens when you are eating, haven't swallowed your food yet, and you involuntarily (usually by a sneeze or laughing) hack up the chewed up parts. Named after the scene in Lilo And Stitch where Stitch regurgitates a cake he was told not to eat.

Dude, that scene was so funny, I coughed out a stitch cake.
