A social networking site user (i.e. livevideo,youtube) that is such a social misfit they have to create 100's of soc accounts to spew hate with their usual fucktardedness.

The user carries on multiple conversations with themselves and the voices in their head via blog comments or liveshow broadcasts. These users are the lowest form of life found on the interwebs and normally reside in Canada.

Person2: Yea he is definitely a fuckmullet from the word go.

A derivative of the Germanic hairstyle featuring a grippable mane at the top or back of the head. Used primarily as something to hold on to during sex, but can also be used for directing a man's head from face-level to muff and back again, without the need for words.
She grabbed him by the fuckmullet and plunged his head between her thighs.
