babble-baby
A babble-baby is like a person who talks so much they forget what they were saying, and then they say something even dumber.
'I was talking about my cat, then I said I was a dragon, then I asked if the sky had a phone.'
Text: 'My teacher is a babble-baby. She said the sun was a pizza and that math was a curse.'
Voice memo: 'I think I'm a babble-baby. I said 10 things, none of them made sense.'
