Beastie
beastie was a playgroundword at my school mainly used by a boy called 'davie G'- he expressed most of his feelings towards people using this word alone, the tone of voice he said it in created a meaning to the word. Beastie ment everything to good-looking girls to ugly two faced boys and was used by many children for around a year!
