blacktuber 

Someone who is usually from an African-American descent that only gains popularity/success in Youtube (And other social medias) because of their skin colour. They follow a cookie-cutter formula of stereo-typing black culture in order to "spice up" their bland and useless reaction videos. Almost ALWAYS will they be uploading ONLY Reaction videos to anything related to Hip-Hop/Typically Ghetto stuff.

"Hey man have you checked out (Black Reaction Youtube Channel)?"
"Nah man, he's just a blacktuber, find some REAL content."
