Here’s a place to collect gifs of the Fi – Excessive Contempt signal, which is described thusly: “One cheek is pulled to the left or right in a contempt signal, but at an irregular time while the person is talking."
The gifs don’t need to show just this one signal in isolation, necessarily – as long as the relevant signal is clear.
Here’s a gif of Amy, who is in the database as FiNe l—, exhibiting what I think might be an excessive contempt signal, but I'm not entirely sure. The movement here is a bit more downward than the gifs in the codifier. Let me know if you think this counts or not.
