Muk (Inuit Staring Game)

Two players kneel or sit facing each other at close range, close enough to look directly into one another's eyes.

On a signal, both players say the word 'muk' and must then hold a completely straight face, staying silent.

Each player tries to make the other laugh, smile, or flinch using only expressions, faces, or small sounds, without touching them.

The moment a player breaks and shows any hint of a smile or laughter, they lose that round.

Players can play best-of-several rounds or run a tournament bracket to find the most stone-faced winner.

A quieter variant has both players stay completely silent for a set time instead of trying to provoke each other, seeing who can hold still and wordless the longest.
