jingo bingo
A game in which you and a friend take adjacent elevators to the top floor of a building, agreeing that when you get there you will jump out and shout "jingo bingo!" without even looking. It is a race, but there are never any hard feelings; somehow the shouting of "jingo bingo!" reduces the competitive edge. Plus, if it is a draw you both get to jump out of lifts shouting "jingo bingo" together, which is a rare pleasure. If you win the race but do not shout "jingo bingo!" then you lose - you should shout it loud enough for your opponent to hear you in their lift.
