Sleeping Burito
This happens when the inside of a sleeping bag contains food inside of it, preferably beef, becoming a sleeping burito that screeches ear-breaking sounds into your ear, usually screaming "EAT ME!!!"
Guy 1: Hey did you hear about that story about food in a bag?
Guy 2: Yeah you mean the sleeping burito that screams at you!
Guy 2: Yeah you mean the sleeping burito that screams at you!
