Did you do a doubletake? In case you're wondering, no that it not a misspelling. I did not choose an F word dealing with sex. Today's word is Formication, which means:
The illusion or hallucination of insects crawling under the skin.
Oh yeah, this is definitely a favorite. If you say it outloud, people around you exclaim, "What did you just say?" in shock or outrage. Then when you explain, they get creeped out as the imagery this word evokes crawls across their mind.
It's kind of funny when you think about it. If you think insects are climbing around under your skin, shouldn't you be more worried about what holes you have (that are large enough to let them in and are probably bleeding profusely) instead of worrying about the insects themselves? Eh, maybe it's one of those moments when sheer panic is acceptable and expected.
Either way, this is a great word.
Do I dare ask what other F words you people can come up with?
