Par ou Impar - Even or Odd
Kind of like the mutant baby between tossing a coin and Rock-Paper-Scissors.
Particularly popular when a group needs a Rock-Paper-Scissors decision but there’s too many people for it to work.
One person calls Odd, one person calls Even, then everyone tosses in their hands. If the number’s odd, whoever had called Odd wins and vice versa.
It’s usually pronounced as if the name of the game was “Paroimpar”.
Fun fact: Par literally translates as “pair”.
