A subset of the YouTube hater that attempts to pwn users with successful channels.
It should be noted that most YouTube haters hide behind their keyboards and rarely post a video, leaving negative comments. In contrast, the pwnabee typically provides a video response, hoping to take down a popular user by some sort of lame disclosure or criticism.
Psychologists have studied pwanabees and concluded that their unusually aggressive behavior and desire for attention can be correlated to either (1) the absence of interaction of any type with the opposite gender (most notably, sexual intercourse) and/or (2) being weaned off of breast milk prematurely.
"I can't believe it! Someone disclosed that Zipster is ... gay!"
"Chill. Just a pwnabee."
