It's really not. It's just current internet lingo. Even twitter uses those terms. We're past the era of broken English in texts, and are fully in the time of phrases taking a new meaning of their own. Nobody uses "yolo" and "lol" anymore, because those were "real life" shorthands. Now we're in the internet-exclusive period. Granted, there is something to be said about the general population's adoption of such terms from imageboards, but that's another kind of talk.
Honestly, it's just fun to write some nonsense and LARP at times. Back in the day that was what the interwebs were all about. If I act here the same way I act in real life, then what's the point of it all, you know?
