Cookie Monster Suprise 

This occurance is the prolapse of a rectum, the process in which the colon falls out the anus, as someone is eating out the butt. The prolasped colon, in turn 'suprises' the person giving the 'anal oral'.

I was licking this girls butt, and then I got a cookie monster suprise. It was so gross.
