The Theory That Everyone Who Jumps at New Year's Eve Has Bouncing Breasts

In my country, there are many people who like to jump at the moment of welcoming the New Year.

And there are also many who mock this as meaningless.

There's no need to look for any deeper meaning than the fact that the impact of the jump makes all the breasts in the country jiggle.

Do you have such a custom in your country?

Thank you for this year. I wish you a Happy New Year.
