Sex act(s) involving a non-scalding steam cleaner applied to the genitals, colloquial to New England
It was wicked good sex; she gave me a winthrop steamer and I blew my chowdah.

I was steamed, cleaned, and vaselined

I had my choice between the vacuum and the steam cleaner and skipped the hooverjob and went with a winthrop steamer
