The 537 sign (also the 5 and 23 sign).

The 537 sign aka 537 hand sign was invented as a greeting by members of the Ek-sen-triks Cluborguild, many of whom were also involved in Discordianism.

It is also the 23 sign. It is 5 (five fingers counting the thumb), 3 (three fingers up counting the thumb) and 7 (three fingers up counting the thumb plus four fingers (two fingers doubled over). So it represents 537.

And it's also 2 fingers down, 3 fingers up depending on how you look at it. So it also represents the number 23.

It is often used in the Bodyshake.
