| the uk names of chasing games played the world over. one person is ''it'' (or ''he''..) and chases the others within the play area - a school playground? - until they catch and touch one of them, who is now ''it'' until _they_ catch and ''tag'' another player, etc. - or the bell (or whatever) sounds to end the play period.
that's the basic game; there are lots of variations, such as ''shadow he'', and ''chain he'', some of which are quite elaborate; and there's an associated body of arcane lore covering how to cope with various aspects, such as whether ''no having back'' does or does not automatically apply unless explicitly varied.
the author of this wonderful website commented that they were always the one left ''it'' when the bell went - and did we/i never think about the fate of the people left ''it'' forever? [it's an excellent website for unsuspected nooks and crannies], and i thought back to my schooldays, when i played such chase games.
didn't you ever play them?
