o//

It is a head with one arm. The two slashes show the movement of the arm. So it's a way of waving someone as goodbye.

It has been around for more than 10 years but isn't used very frequently.
Often the shorter version o/ is used instead.

Frank: I g2g to bed now.
Lee: Okay, sleep well. Bye o//
Frank: o//
