At any location with a trough style urinal that is designed for use by more than one person, the House Boy is required to display his buttocks by lowering his pants and any underclothing to at least the bottom of his butt cheeks or to use a ‘seated stall’ subject to the rules for stall usage. To prevent spillage or splattering on others who may use the trough urinal, the boy is permitted to use one hand to hold and aim his penis, and one hand to balance himself while urinating. Outdoor and non-trough urinals are covered under a different rule.
