Didn’t see it mentioned in the wiki. When the middle finger was gaining popularity, during the 80’s in my circles, using the middle finger folded in half was a thing mentioned. I guess with the description in the wiki that makes sense as it infers that the person being insult has a tiny dick. I remember someone mentioning it was a Greek insult, but never knew it had a history. TIL.

Now I get spammed by a hundred Greeks telling me they have never heard of it. :) In my defence, we had no internet when I was young. There was no way to check on BS Vs fact.
