a LOON is to "Laugh Out Of Nose". When people say LOL or to "Laugh Out Loud", most of the time they actually LOON. Think about next time you supposedly LOL, I bet you will actually LOON.

Dave and I grabbed a 6 pack of Busch and headed down to the lake for some looning. Little fight, no bite.

In Aberdeen, Scotland, it's local dialect (doric) meaning a young guy. That's probably why there's another definition further up, for fans of the Scottish actor Billy Boyd. Whose not from Aberdeen I think but never mind.
