Someone who doesn't need drugs for a high they only need a big dirty stinking bass. They may be seen dancing eratically and fist pumpinglike there's no tomorrow in clubs. They can be misinterpretted for a bass junkie but they are infact bassline junkies that only get high off music.
also called niche music, and popular in the north of england, it's like old skool speed garage with filthier basslines and influences of electro, 2step and drum and bass.
several RnG/Grime and UK urban tracks have been given a niche remix.
