- n. A non-playing member of a rugby union club who helps in the running of the club by performing various roles, usually on match days. These roles are not committee positions but are essential if the club is to function properly.
Legend attributes the term to former Irish full back and captain Ernie Crawford, who was rumored to remark on a book read by a teammate by saying "You and your bloody Ali Khadu." Another possible origin dates from the amateur days of the game, when hard-pressed club helpers, when asked for more balls, players, games and etc., the reply was "it's all I can do". Hence alickadoo. (Wiktionary)
