what it is: you are an idiot
where i found it: north korea (maybe)
You probably heard about the hack attack on Hollywood (possibly) coming from North Korea in retribution for a fictional scene of Kim Jong Un's head exploding. North Korea says they didn't do it and also that the attack was only the first of their efforts (?). At any rate, the group behind the attack, known as the Guardians of Peace, sent this little video, titled You Are An Idiot, to the FBI over the weekend. It's worth watching because you are an idiot.
Also, I believe the acoustic version of Idiot Wind to be superior to the electric version.
