What is a twertle?

"Twertle" is not a recognized word in the English language. It's likely a made-up word, perhaps a misspelling of a real word, or a slang term specific to a certain community or group.

To help me understand what you're looking for, could you please provide more context?

For example:

* Where did you hear this word? (a book, a movie, a conversation)

* What was the context? (what was being talked about)

* What do you think it might mean?

With more information, I can try to figure out what "twertle" might refer to.
