1.) (n) A typically substandard dwelling that is likely to be, or has been the scene of a (multiple) rape(s). Classification is based primarily on the building's appearance.

Though usually an abandoned hovel in the country, inner city rapeshacks can exist as well.
2.) (v) To violently rape, either literally or figuratively.
