Bro Plank 

The "Bro Plank" is a term used for a balancing act done by two people wherein one person gets into the push up position and the second wraps their arms around the chest of the person in the push up position and with their feet in the opposite direction they simultaneously lift their feet of the ground and act as a cantilever for each other. The final product will be two hands touching the ground and two bodies balancing off of the hands.

The inventors of the bro plank can been seen on youtube under their channel name "sundayfundayz"

Those two bro's were bro planking outside the skytrain station today.
