A person who comments on Youtube videos and uses excessive slang, poor grammar, and generally presents him/herself in a douchey way. May also post for the sole reason of cutting down the video poster because they inexplicably "suck," or to simply annoy others or start an argument.
Crappy Youtuber: "Eww...i hate this stuff...this is the first video i've seen of you...DONT like it...sorry "
Great Youtuber: "What a pointless comment. You're such a youtuchebag."
