Do you call your kids something specific when they're being bad/whiney/frustrating etc?

When my son is being difficult I used to say 'son' or usually I drag it out 'sonnn!' Which turned into '"son"shine' (see the pun? Haha) so whenever he's doing something frustrating, or whining, I call him Sonshine. A bright, sweet nickname for times that aren't bright and sweet, haha
