The unfortunate event that occurs when comsuming a beverage (milk, usually) and due to a joke or other funny event, the act of trying to supress the mirth results in the liquid spraying out of your nose.

I was watching Jim walk down the street and while I took a sip of milk, he fell down the steps, causing me to have a noseblast!
