What's really disturbing is that he had to put 455 on there. Because, apparently, there were already too many eatdatpussy's registered on YouTube?
Not really disturbing, but more of people who are telling you what's specifically on their mind. I'm guessing it's like a new age battle cry, instead of "Charge," "Yo, Joe," "Remember the Alamo," or even Xena's battle cry (would be too girl for a guy, maybe). They subconsciously settled on, "Eat dat p***y." It sort of sounds like "Whup that trick," from Hustle & Flow, but much nastier, to the point, and getting ready for battle.
