"I used to be with "it"! Then they changed what "it" was! Now what I'm with isn't "it" and what's "it" is strange and confusing! AND IT'LL HAPPEN TO YOUUUU!"
I think that it was something of a blessing in disguise that I was never cool.
Even within Transformers fandom, whatever clout or regard I had in the turn-of-the-millennium was (I learned) somewhat conditional.
Anyway, as a result of not having a real place to belong, I could be more of a detached observer of internet culture, and so I had a front row seat for a lot of the Internet's effect on parlance.
Cultural fragmentation is a thing, of course, so it's not as though I use every meme old and new or get every reference, but looking back it's kind of funny (in both senses) how many I collected, as a sort of jackdaw of pop culture.
Oddly enough, steering back to Transformers using Internet terms (or not, depending on what they find), I remember a lot of suggestions that Rumble and Frenzy of all mechs might talk like 4chan's /b board back when it first shot to prominence in the early aughts.
