flibber jibber 

A dumb person, or someone that just did something dumb, made a dumb comment or had a dumb idea.

That's a ridiculous idea, flibber jibber.

Flabber Jabber

When you've been so exasperated you don't even know what to say about someone anymore, so you pull out the most immature and stupid thing you can in the moment. Mainly used in moments like if someone just stuck the landing from the roof of a three story building to the ground without breaking a bone, or if they're just so good at something you literally can't criticize them for it at all.

"WHY THE FUCK DID YOU DO THAT?! *mumbles* Flabber jabber... Christ..."
