Damn it never thought this would happen to me. I was doing my second set of shoulder shrugs with 80lbs, and after I was done i racked the right dumbell and i thought the same went for the left, but it slid and pinched my skin between the dumbell and the rack. dunno if i should pop it and apply neosporin or wait for it to fall off eventually. It's def. full of blood now. Sorry if large pics.
