The "great eight" filler words whose meaning the people using them don't even understand, but solely spam them on every YouTube video they can get their hands onto, because "that is what you are supposed to do!" These people probably (I don't want to know) use this YouTube/Reddit/add-your-site-of-choice-here meme language in real-life situations too: at school (if they attend to one (hey, everything is possible)), in a line at a supermarket, at the mall etc. It must be spoken loudly, so people around can hear it the same way everyone sees their comments on-line.
The Great Eight filler words are: honest(ly), literally, appreciate, underrated, legit (short for legitimate), ignore, actually and though (short for although). Notice that "legit" is NEVER written as "legitimate" and its meaning is NOT "legitimate" but "legitimately" in this age of newspeak and memetalk. "Though" is never written as "although" and it has NO meaning whatsoever; it's a 100% bona-fide filler word. Summa summarum: it wouldn't make a difference if you wrote "onionballz!" instead of "legit" or "though", as anyone with a functioning set of brains just omits; passes these empty words with no meaning or value.
Melvin: "Nice to see a new video from The Rolling Stones though. Let's be honest and stop ignoring the fact that they are legit the most underrated band in the world. SMH."
Sparky: "Facts. The Stones literally is sooo underrated that it hurts, to be honest, actually."
Thor: "*ambiguous smiley* Anyone else here for they actually appreciate the music though?"
Alfred: "Anyone watching in 2021? I wish this pandemic was over..."
Bob: "Gee, guys! Ever heard of The Great Eight?" ¦D"
