Barrow boy is a British expression with two meanings, occupational and social. Street traders since the 19th century (and perhaps earlier) sold seasonal goods (especially vegetables) from two-wheeled barrows. London street traders were called costermongers (from costard, the mediaeval word for apple) and more generally barrow boys, since anything could be sold from a barrow (including clothes, crockery, etc.) In more generic terms, a Barrow boy may also refer to a boy from a place called Barrow.
