I’ve defo seen it before, some player used to do it in the 80s, but I don’t know if it was since outlawed. It made such a cultural splash that the seminal tv series The Manageress, starring the delectable Cherie Lunghi (still would), featured a player who did it for her side.

According to google they're still legal but I have to agree I haven't seen one for ages. They're probably a bit like that scorpion kick thingy the Columbia keeper did. Brilliant if they come off but you look a bit of a nob if they don't.
Boring ****.
