Leg
In the Victorian era, legs were so private that the word “leg” itself was considered a swear. According to Deseret News, “At the dinner table, it wasn’t acceptable to ask for a leg or a thigh of chicken, which is why people started using the term ‘dark meat.’ (People also put skirts on tables and beds, so the furniture legs wouldn’t show.)” Other polite substitutes for “leg” included “limb.”
Barbarian
This was the Greeks’ catch-all term for foreigners. “They thought that Greek wasn’t just the best language, it was the only language that made any sense at all,” Cracked reports. “All other languages just sounded like people saying ‘bar bar bar bar.’ Thus the word ‘barbarian.'”

Seminar
Pretty much every word preceded by “semin-” is just as etymologically dirty as you’d think. “Seminar comes from the Latin term, ‘Seminis’ which means semen,” says Cracked. “This is used figuratively because it is a spawning ground for ideas… Likewise if you ever hear some important person referring to a ‘seminal’ moment or idea, same thing. It’s the ejaculation that gave birth to something new.” That’s actually pretty poetic, to be honest.
Bull
This word was also off-limits in the Victorian era for its association with male fertility; apparently “polite people said cow brute, a gentleman cow, a top cow, or a seed ox.”
Vandal
It’s hard to picture this word as outright offensive, as it refers to someone who defaces property. But so does its original definition: after the Germanic Vandal tribe invaded Rome, the Romans decided that it was a good name for all destructive types.
Golly
This hasn’t been a serious swear word for a long time, common as it was among comically innocent TV kids of the ’50s and ’60s. However, it used to be considered legitimately blasphemous, as it’s a contraction of “god’s body.” Shakespeare didn’t shy away from the word, and his use of curses like “golly” made them seem a little less edgy, according to io9.
Trousers
While “trousers” sounds overly proper in modern times, this was another word polite Victorians didn’t use. Instead, they called their pants by such catchy alternative names as “inexpressibles,” “nether garments,” and, um, “sit-down-upons.”
Scumbag
“Scumbag” may seem harmless these days, but The New York Times was wary about printing it after Indiana Representative Dan Burton used it against President Clinton. Why? It originally means “used condom,” and the publication didn’t want to offend older readers.
And the testicular words keep on coming! “Avocado” is derived from “ahuacatl,” the Aztec word for “testicle.” This also extends to “guacamole,” as its translation in Nahuatl is basically “testicle sauce” — but that won’t stop me from eating it.
