Common prison slang for a pedophile. If you're tagged as that, you're in for some serious beating from what I hear.

If there's one kind of criminal inmates hate the most, it's pedophiles. Even in prison, there is a pecking order among the interned and child molesters are at the bottom of the scale. The other criminals view them as monsters rather than another criminal. They get probably the most injuries, and in many cases, death at the hands of other inmates, they think it's the sickest crime. That may be because a disproportionate number of inmates were abused as children.
