Heavier Than Thou 

A way of saying I am more metal than you are, or to claim that something is TRUE METAL. This is a play on the saying Holier than thou.

Have you heard that The Showdown has reunited?? Their new stuff is heavier than thou!!!

Have you heard that The Showdown is back?? Their new stuff is heavier than thou!!!

headier-than-thou 

A person who is headie or heady or a head (ie into the jamband scene) and believes they are better than other fans because they have been to a large number of shows, tour extensively, know a great deal of statistics by heart, wear a lot of patchwork, or are extensively organic--anything to do with the jamband scene. Essentially a jamband snob.
Just as “holier-than-thou,” is a word one would use to describe someone who believes they are better than others for their moral points of view, the person who is “headier-than-thou” thinks s/he is better than other fans because of their level of “fan-ness,” or at least this is what other heads believe the “headier-than-thou” person is communicating through their behavior.

That guy won't shut up about how many Phish shows he's been to. He is so "headier-than-thou."
