One counter-example is that Japanese Twitter users used to strongly dislike quote retweeting for a few reasons. Some view it as unnecessarily combative, whilst others (if they're retweeting art, as an example), view it as stealing likes and views from the artist's tweet. In the latter case, the accepted practice is to retweet the art, then make a post "LRT (last retweet): blah blah blah" with whatever they wanted to say about the art. This practice has actually entered some sections of Western Twitter spaces. Well, almost exclusively weeb spaces for obvious reasons.

The troll-face meme is a good example of this phenomenon. It was utterly dormant from like 2016 to 2020, then it was revived on TikTok by third worlders seeing it for the first time. Although even on TikTok, it ended up being used in a mostly ironic manner eventually, mirroring phonk.
