content: youtubers copying others.Same thing with people using popular phrases. like "cash me outside" or "real talk" or "catch a fade"  They hear others say/do it and think its cool and want to be in on it to. One in particular is the long articulated first word in a youtube intro. ie "Welllllcome" "Wuuuuuuuuuats up its captain fizzywins-make-sure-to-SMmmash-that-like-button-I-waist-7min-toget-to-the-actual-point-and-POSSIBLY-the-thumbnail-here-we-go!"
