This might be the most impressively complicated handshake you'll ever see

The only thing better than a solid handshake is a solid secret handshake that can't be duplicated.

Twitter user @MelynnaPena shared a video on Sunday that shows her younger sister and a teacher engaging in a minute-long sequence of movements and motions that make up what might be the greatest secret handshake I've seen in the history of handshakes.

"My little sister and her teacher had a handshake from the beginning of the year and added to it every Friday til the last day of school and here’s the end result," Melynna wrote on Twitter.

It's so impressive that it's worth watching twice to catch all the excellent moves — like the brief lightsaber battle that happens and the cute phone maneuver.
