For whatever reason, "Bluey made me ugly cry" is a very minor meme among parents on the Internet. I've seen it elsewhere too.

I find it disappointing that a pretty common emotional state for a person is labelled ugly. Its negative so I'd rather people not use it.

It just means that you cry so hard your face is all twisted up and you go red and and your mouth is hanging open and there's snot dripping out of your nose, as opposed to simply shedding a couple tears. It's not really disparaging.

Thank you for being the person that got around to actually describing/defining it !
