Dwayne Johnson, aka The Rock, threw an amazing birthday party for his mother’s 75th birthday.

The 51-year-old Hollywood star shared a clip of the birthday party on his Instagram, and there’s one thing that stands out.

You’ve got live music (and The Rock is dancing, of course), traditional Samoan dresses and… money being thrown around.

Apparently, this is a Samoan tradition to show appreciation to the dancers.

“Customary to throw money as I did at my mom — and my dance, ‘Aiuli’ is a sign of respect and pride,” the post caption reads.

And don’t worry, those bills are actually fake.
