quicko: to spit the dummy

Betcha don't know what that means!

Okay, we're good on "to spit"? Cool. "The dummy" then translates to "the pacifier." (It's really just what they call them, don't ask me why.) Closer to understanding? No? All right then: when does a baby spit its pacifier? Answer: when it's very angry and throwing a temper tantrum. Thus, to spit the dummy is to throw an adult temper tantrum -- a hissy fit. It doesn't actually have to be so extreme, but that's the idea.

So, yeah. Don't spit the dummy about it.
