Toddler Swearing

Because Celeste is a toddler and has no swear words for when she gets annoyed, this week she's been creating her own. Imagine these shouted by a pig-tail framed cross face and you get the idea. Translations required, please.

• Fatcha-batcha!
• Fireworks!
• Fireworks on you! (accompanied by a throwing hand movement)
• Vasha-wazza-vazza!
• Scap! (also accompanied by a throwing hand gesture)

It's extremely cute, but laughing at her about it rarely makes the situation any better. I said "No...fireworks on you!" one time as a joke and she started crying. I am not a good parent. I'm not even sure what I was apologising for.

I assumed that it's explicit. I have no idea what any of them mean.
