Drinking hot coco too quickly such that it shoots up your nose and burns your internal nostrils. This causes such pain that it causes a large whooping sound and induces tears.
It is not the same thing as doing it with Tea, Coffee, or another Hot Beverage. It must be Coco.
Dave made pat laugh and snort coco through his nose. Man he really was Pulling a Mulhern when he started screaming "my nose, my nose, ahhhhhh it burns and everything smells like chocolate...help meeeeeeeeeee"
