adj. (slang)

Used (mainly) to describe the state of drug users after a few too many lines/pills/tabs/hits or combination thereof. Once a person's lower jaw takes on a mind of it's own, seeking only to meet with their eyebrows and beyond, they're Guernsey. That being said, Guernsey is so much more than a word for gurning.
It may also used to describe when something goes badly wrong and variations of this word are perfectly acceptable. For example, please feel free to add an -ing to make a handy verb for any occasion.

Guernsey is also one of the Channel Islands, which is just fine by us.

Looking for an island full of degenerate retards? You've come to the right place. With the States of Guernsey blowing millions a year on their retarded population (who refer to themselves as 'Donkeys'...) and reaching no reasonable standards (because they're useless!).
Person1: "heard of that stupid island? I forgot what it was called..."
Person2: "oh, you're thinking of Guernsey!"
