Back when it was unlucky to have women aboard ships. The crew needed a solution to their sexual needs. This task was assigned to the 'Pitboy' (usually around 12-15 in age) who would take up position on one side of the glory hole while he 'serviced' the crew members on the other side.
Shut up you duck butter gargling pitboy or I'll castrate you with a nail clipper.
