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.
