1. None of the sources in know your meme are using the term "ratio'd". It's a very specific and modern term used commonly on x.com and it has nothing to do with replies. I already sourced it with a link.
2. Same issue
3. Have nothing to do with x.com
The user said "that's the definition of being ratio'd". Sorry but take your L.
If you go to x.com right now and search the word, numerous examples will come up showing that people are talking about tweets where the reply has more likes than the tweet it is responding to.
