Billingsgate 

coarsely abusive language

was once the name of an actual gate, located in London. It was the site of a fish-market, which took on this name in the 14th century. The market was famed for the vulgarity of the fishmongers’ speech, and so billingsgate came to be synonymous with abusive and coarse language.
