I was actually thinking about this when playing Triforce Heroes and Tales of Zestiria as well.
Even though it's not something I like, I kind of decided that I shouldn't make "the Internet" and Internet jargon into some exclusive, untouchable thing that nobody should be able to reference. I mean, it's true that in all types of media today, we try to avoid even the oldest and most common "Internet" phrases such as "lol" and smilies. In that way, maybe the writers of these games are rather forward thinking, by accepting the fact that we do say these things in real life.
The only thing I'm really worried about is the timelessness of these "Internet" memes and phrases. Ten years from now, will we be saying the same things? Will it make sense when I play the games 20 years from now?
Now don't get me wrong, a piece of media can choose to not write with timelessness in mind. TV shows, movies, games, etc. are sometimes are written with current events in mind. However, Zelda and Tales usually aren't, so it is my worry about the whole thing.
I should note that in Zelda's case, the story is already nonsensical, so the whole "timelessness" worry is minimized. The developers of the game clearly had a bit of fun making the game, taking creative liberties, and NoA's Treehouse is doing the same.
