the flag game

A game played by exchange students (especially Rotary Exchange Students) around the world.
If you kiss a person, you receive a flag of their country. Goal is to collect as many flags as possible during your exchange year.

Variants of the game include different medals for handjobs, blowjobs and sex.

“I kissed an Australian boy! That’s a new flag!”
“Girl, you’re really good at the flag game!”
