Get the mug
Get a Rock-tard mug for your buddy Beatrix.
a relatively unknown non celebrity who is involved in music (although not many people know or care for it)and seems to think they are in legendary status and behave like they are a rockstar. Live in fantasy land inside their own head, population: 1.
changing ones first name to "vegas", then going on stage during a gig in a v small town and announcing the new name to the crowd of 5, is a beautiful example of a rocktard..

Get a Rocktard mug for your boyfriend Jerry.
in short: poser!!!
in long: a person who thinks they are rock because they bought a green day album and a band t-shirt. these people are just basically townies except they have the intelligence to except other types of music other than dance. rocktard probably has a friend who listens to rock music.
person 1: hey check it out im a rock chick!!!
person 2: *cough* rocktard *cough*
