Foursquare has compiled a list of the 20 rudest cities in the world based on the percentage of curse words used in check-in recommendations. Foursquare only looked at English speaking countries and cities with over 1,000 tips.

Of the top 20, a whopping 18 are in the US. Rising to the number one position is Manchester, UK. Californians definitely vent on Foursquare: seven California cities made the top 20.

Believe it or not, there Manhattan did not make the list, although Staten Island, the only New York borrough to be on the list came in at 17--beating Boston by two slots. And the apparently potty-mouthed seniors down in Boca Raton helped to rank it 12th.

1. Manchester, U.K.

2. El Paso, Texas

3. Pittsburgh, Pa.

4. Bloomington, Ind.

5. Riverside, Ca.

6. Tempe, Ariz.
