Apparently, yeah, it totally was!
Gropecunt Lane was a name used in English-speaking towns and cities in the Middle Ages for streets where prostitutes conducted their business. In most cases, the name would appear to derive directly from the words grope (sexual touching), and cunt (female genitalia).
Huh. We're trying to think of a filthier name for a street and we can't. Possibly. What? Cooter Lane? Cocksucker Place? Seriously! We're trying here! We got nothing! Stupid actual life!
