Once a general market which probably sprung up in the 13th century, Billingsgate became a fish market in the 17th century. In Old English, “Billingesgate” refered to the gate of or belonging to the man named Billings, and may have been a gap (gate) in a Roman wall along the river. Perhaps Billings fished the river and brought his catch up through the gap to hawk it to passersby! Who knows?
But of what interest is a market to a word nerd? Well, because the market was once known for the foul, coarse language of the fishmongers who sold their wares in the market, the name of that market has become synonymous with such language. According to Dictionary.com, billingsgate is a noun from:

This tendency of the fishwomen of Billingsgate to use such language also gave rise to the word “fishwife,” a coarse, vulgar woman, likely to outswear a sailor!
So the next time you are in the market for fish, do mind your tongue!
