I have a baby brother and because he grew up with these anime series, I also know them quite well now. I started it once – pokemon jokes.
Mostley it is just adding the ending “-or” or “-i” to a thing of daily use. For example: vacuum cleanor!
I think it is really cute when he adopts something of me.
Regrettable he also stops some habits because of me.
When we met, the first text messages always ended with “xx”. I really liked it, but I never wrote back that way. I don’t know, it just doesn’t feel like me. So after some time he stopped using this/his phrase and adopted mine. It’s a pity.
I should ask him if he has noticed any adoption of my habits during the time we know each other.
