It looks like they are reaching out to grab a piece of candy or something. I am always interested in how language and signs (both verbal and non-verbal) evolve and how people mimic each other without thinking.

Have you noticed this trend with this finger gesture?

Answer 1

Weird, maybe a secert sign of the devil or something.
