Would be great if an extra hand signal can be added to explain that a foul is a strip foul. This would be helpful for commentators when dissecting a call during a discussion and would be good for the rest of the field to know if the result would be a goal or not if the call is accepted or not.
It’s not official but for a strip foul, a lot of people do the foul hand signal first, followed by rubbing their top forearm/wrist up and down the other forearm. I always understand that this to be foul – strip.
