cuted out
Cuted out is what happens when a cat, dog, or baby (usually) does something so absurdly cute that your brain stops working and you start saying things that aren't actually words and talking in baby gaga voice.
Boy: Why did you stop what you were saying mid-sentence?
Girl: OMG somebody sent me a video of a cat inside a cat costume playing with string. I was temporarily cuted out.
