A Colbourne is someone who has, opinionately, very bad smelling socks. These socks are usually blue, or red and blue; sometimes the socks aren't washed for weeks on end, or even months. A more "full" Colbourne is also someone who is pretty good in goal at football, has weird sayings like "fair deuce", and seems to get on with everybody, especially girls.
