Adjective. - Used to describe a person, action or object that is very cool, impressive or outstanding, when ‘cool’, ‘awesome’ or ‘epic’ are considered too mainstream to describe it. An open dig at ‘Hipster cool’ jargon - taking a word that means nothing out of context and using it as your cool word.
‘That Keyboard Cat t-shirt is well Borneo.’
‘That electro band I saw last night before you were proper Borneo.’
Verb. (Muttleyed, Muttleys) - To Muttley means to find something so funny you can only respond with a strained wheeze, making your laugh sound like the character from Wacky Races;
‘Awesome, that made me Muttley’
‘I enjoyed it so much I Muttleyed’
‘He Muttleys every time he sees it’
