A small measure of an alcoholic drink, most noteably half a pint. Named after the Coronation Street character who only drinks half pints of beer. Used mainly in a mocking/banter way between young groups of males. Can also refered to simply as a 'ken'.
To order a half pint of beer in the pub one might say 'Could i get a ken barlow please'
