50 Words That Sound Rude But Actually Aren't
To paraphrase Krusty the Clown, comedy isn’t dirty words—it’s words that sound dirty, like mukluk. He’s right, of course. Some words really do sound like they mean something quite different from their otherwise entirely innocent definition (a mukluk is an Inuit sealskin boot, in case you were wondering), and no matter how clean-minded you might be, it’s hard not to raise an eyebrow or a wry smile whenever someone says something like cockchafer or sexangle. Here are 50 words that might sound rude, but really aren’t. Honest.

Here are five that caught my eye:

CLATTERFART - According to a Tudor dictionary published in 1552, a clatterfart is someone who "wyl disclose anye light secreate"—in other words, it’s a gossip or blabbermouth.

DREAMHOLE - A dreamhole is a small slit or opening made in the wall of a building to let in sunlight or fresh air. It was also once used to refer to holes in watchtowers used by lookouts and guards, or to openings left in the walls of church towers to amplify the sounds of the bells.

FANNY-BLOWER - According to one 19th century glossary of industrial slang, a fanny-blower or fanner was "used in the scissor-grinding industry," and comprised "a wheel with vanes, fixed onto a rotating shaft, enclosed in a case or chamber to create a blast of air." In other words, it’s a fan.

PAKAPOO - Pakapoo is a 19th century Australian word for a lottery or raffle. It apparently derives from a Cantonese phrase, baahk gáap piu, literally meaning "white pigeon ticket"—the Oxford English Dictionary suggests that in the original form of the game, a white dove might have been trained to select the winning ticket from all of the entries.

TIT-TYRANT - The tit-tyrants are a family of eight species of flycatcher native to the Andes Mountains and the westernmost rainforests of South America. One of the species, the ash-breasted tit-tyrant, is one of the world’s most endangered birds with fewer than 1000 individuals left in a handful of remote, high-altitude sites in Peru and Bolivia.
