A once-common game played mainly by boys in their first year of
secondary school at Inverkeithing High School in Fife, Scotland. When on a crowded double-decker bus, one must stand at the bottom of the stairs between the two decks and not move. Others will stand behind you, and as many people will try to cram themselves into that tiny
little space as possible. Some will get a bit too excited, attacking people and jumping
off the top deck, inevitably leading to a riot.
