Perfect segue to the toothpick guy. There are lots of them.

After food, out comes the pick, and the guy is mining for nuggets for 5 or 10 minutes. That's bad enough, but then comes the "oral fixation" stage, where the same toothpick becomes a wobbling distraction while he sucks, gnaws, and fiddles with and on it for hours, like a bad 1950's movie hood.

I really don't want to see a wobbling piece of wood hanging on your lip every time you talk. May as well stick a big piece of broccoli between your front teeth.
