https://en.wikipedia.org/wiki/Flanderizationalso IMO, because the nature of watching a streamer is that 99.9% of what's going on is boring or normal/regular shit, if they happen to say or do something even slightly quirky, that little glimmer of oddity gets noticed and perhaps preserved.
even though a streamer might actually do and say several odd things, I notice that usually it's stuff when they're new that tends to get immortalized as their permanent quirks even if fucking years go by. you can probably still find people doing the "a" thing for Gura even though she only ever did that for her first like two, three weeks several years ago and never came back to it. ant brained fans and newfags wanting to fit in keep it alive however. also, because people want to be entertaining within line of sight of a streamer to try to be noticed by him/her, they repeat it over and over. thing is, the average watcher is not the talented or funny one and has no grasp of the tact of well-placed humor and what the time and place for it is, and if they're some stupid faggot 11 year old they have no idea that what they're doing is fucking hyper cringe and it seems chat is often not self-aware enough to stop it. the streamer usually is going to be too polite to ask them to stop, or know that maybe their audience will only do it 10x more if they point out that it annoys them depending on what kind of viewers they have.
