Most everyone curses but some people do it really well. For example, we all know how to liken someone we don’t like to a specific body part but only some people know exactly which body part to cite in order to describe a personality to a “t”.
I can think of cursers who are famous for their timing, and/or the creativity of their epithets but I can’t remember someone whose insults proved them a wise judge of character. And, yet, I’m sure such experts exist.
