Knights of the road
Tramps who line our streets drinking such delights as Special Brew, Tennants Super or White Ace cider. Usually sporting an unkempt beard and a fresh open wound from falling over drunk. Often stink of their own piss and shout manic abuse at innocent passers-by.
"His drinking is getting out of hand, if he carries on like this he'll be one of the Knights of the Road before he knows it."
