The majority of modern heavy metal. Music which is thrashy for the sake of thrashy and usualy played by complete idiots.

Usualy played in drop D (a guitar tunning acheived by by loosening the low E until it is a D) as the name would sugest, but can be played in any drop tunning.

Most riffs will consist of 2 to 4 bars of beefy low end crunch, followed by a quick Dime squeel. Lyrics will either be growled or sang in a wingy moany fashion similar to crying. Drummer will usualy play with a double bass pedal and a chineese ride symbol.

Common characteristics include: Not being able to tell riffs apart from each other, not being able to tell songs apart from each other, not being able to tell bands apart from each other.

Get the Drop a D mug.
When a guitarist drops the low E string down to a D, usually implying he's about to look like an ass playing power chords.

This, however, excludes D Standard tuning, where the guitarist will also drop the B string to an A, and the top E string to a D as well.
Judgmental Person A - "Hey, this guy sucks at guitar. But let's stay and watch anyways for the fun of it."

Judgmental Person B - "I know dude right?"

Judgmental Person C - "Oh damn, he's dropping the D. I can't wait to see this."

An alternate tuning for the guitar, CGCFAD as opposed to EADGBE. More commonly (and mistakenly) referred to as Drop C.

Many bands utilize this particular tuning, including, but not limited to, As I Lay Dying, Killswitch Engage, System of a Down, Children of Bodom, Lostprophets, Breaking Benjamin, Bullet For My Valentine, Rammstein, Atreyu, Senses Fail, From First To Last, Metallica, Norma Jean, Thrice, A7X, and The Red Jumpsuit Apparatus.
Bill: "Dude, I love how Atreyu plays all of their songs in Drop C!"
Bob: "No man, they play in Dropped D Tuned Down One Whole Step."
Bill: "Dude, that's a long ass name. Lets just call it Drop C."
Bob: "OK."
