I think if you get off the ice, you're OK. I imagine they can't run fast with ice skates on.

I was "jerseyed" once when goofing around fighting with a friend. Man that sucked . I felt like an idiot sitting in a bag getting punched.

One thing to try could be to slip out, like Ryu said. That is if your sweater, jacket, shirt, etc. is loose enough, and that is all the person is grabbing. When you're free you can then flex your now exposed muscles and try to get some phone numbers from chicks. Unless those chicks saw you getting jerseyed. Probably not much hope then.
