Usually uttered/bellowed in situations of enormous bordem and/or insanity.
Dates back to the times of "King Glegluna" (1376 - '84 - Mongilia)
The word was bellowed through a large horn, which marked the day that it was legal to breed Wombats with Grey Hounds.
Look forward.. nothing.. stillness.... when all of a sudden you see something move in your peripheral vision to your right.. you look over and your friend is looking at you with a look of crazed insanity mixed with desperation.. he looks forward, takes a deep breath and lets out a bellowing.... "SHOOOOOORRRNNSSSS!!!"
2) a word that may provide a code name for a certain person, place, or thing.
eg. Man 1 - "Where are you going Frank?"
Man 2 - "Settle the fuck down Steven! I'm going to Shorns house to get a cappucino, you comin?"
As you can see in this particular scenario, "Shorns House" has been applied to the word "Maccas", or "McDonalds"
