Clumsy. It always bothered me that Sims just "laugh at themselves" instead of getting Embarrassed. I think it's been tweaked at some point so it's a tiny bit noticeable now, but it's one I always felt didn't do much.
Oh, also, I agree about Evil. Evil was always a little disappointing, as Mean seems more Evil than Evil, lol. I've given several of my Sims the Evil trait though because the laugh is funny to me and it amuses me to see them smile when another Sim is unhappy, lol.
Another one I'd choose that's a nothingburger is the Good trait. Does that do anything at all besides react kind of negatively to Evil Sims? I hardly ever use this one.
