It was just the number 3. Case closed. All the Jeopardy contestants joining in on the witchhunt should be ashamed of themselves.
What was weird is all the people insisting that no one ever makes 3 like that, using the pinky instead of the index finger, but I usually do, since I have to hold down the pinky with the thumb, but making 3 like that requires much less effort since the index finger can stay down on it's own. Like people just assumed that their own gesture for 3 is the same way everyone does it...
