Thanks for the suggestions all. Accurate and annoying is exactly what I'm going for here.
I'm a little worried about Gen-x though. I could see it just getting shortened to X-Clark and X-Lois and the whole 'X' thing might be too evocative of Lex and too, too irritating!
I think I've come up with something very irritating, annoying and hopefully clever. We'll have to see if it works in the story. It's not integral to the plot or anything but it's a fun little aside.
