The slang term 'Keeth', sometimes spelt 'Keith' or 'Keth'. Is a British word used by teenage boys and girls. It is a word used to describe a male (usually) that is very un-cool. A keeth follows ther rules, a keeth has bad dress sense, a keeth dosent get any girls. Being called a Keeth is far from a compliment.
