To sneak up behind someone wearing a hoodie, then inverting the hood on said hoodie, thus making it appear as though the person now has a shark fin on their back.

This can then be accompanied with shouts of 'SHARKED! SHARKED!' at the victim while simulating a shark fin on your own forehead.

You can also mock them further by, for example asking 'what is your favourite film?' and then hilariously answering it yourself with the response 'JAWS?!'

Sharking was invented by Tom Brown in 2010.
