Knash 

The name Knash is derived from the greek god turbo master. Knash's are generous and always looking to make you laugh, even if it invovles licking another mans nipple. They will always want you to succeed and remind you always to knit yourself a somebody! Knash's usually like to play card games and will win at every game you challenge him at. If you treat him really good he will buy you a tasty noog. Nicknames include: turbo mangler, beer slayer, knashed potatoes, knashole, frankenknash, hash martens

massive knashers 

Someone that is a specky cunt and has no friends, usually joins in with things that you haven't asked them to do like butting into conversations or turning up to things that they weren't invited to. And has MASSIVE fucking teeth. This is a direct link with having massive 'knashers', glasses and being an annoying cunt. This usually occurs with someone that has a really overused and generic name like Jack, Callum or David.

*tries to insult you with his massive knashers knowledge*
"Fuck off ya specky buck toothed massive knashers rabbit." Or the occasionally
"Can you get Sky Sports on they Knashers?" or if you want to really piss them off go for...

"Goin eat some carrots ya specky cunt and take yer Shan patter and loneliness with you ya rabbit fuck"
