I thought the same. A bit of story telling... My girlfriend and I have switched half of our conversations to internal memes to express how we feel or feel about something, especially with small conflicts that arise from everyday life. I guess most couples do that to an extent, though I think spending so much time together last year (COVID19 working from home ) increased the "meme communication".
Hehe, one of the cool things about learning each other's spoken languages, is you get more memes, in other languages. I have a handful of fun Chinese phrases to whip out like "you're effin' annoying" or ways of calling each other idiots :)
