Pulling the foreskin of an uncircumsized penis over the skin of a circumsized penis in order for the person that has been circumsized to know what it feels like to have foreskin on his dick.
David: What you doing tonight?
Scott: Probably just going to sit at home and dream about having foreskin.
David: Why don't you come over to my place and we can Share Hats so you can feel the real deal.
Scott: I got AIDS from the Jonas Brothers.

Girl 1: Did you get the ride lastnight?
Girl 2: Yeah I had 1 too many WKD's and ended up Sharing a hat in the disabled toilets of the club!
