Bass Nightcore

Bass Nightcore is like nightcore, but fast beats, the main melody (and voice) are pitched up, but there's very low bass added; so the contrast between very high and very low is created.

Person 1: Hey dude, do you like nightcore?
Person 2: Nah, I like bass nightcore better.

Bass Driver 

1. A person with no thought of their own who just follows trends. 2. A person that drives the same vehicle as everyone else, tricked out in the same way, who thinks this makes them cool. 3. A person who wakes of their neighbors by playing the same-old, generic rap music.

Bass Drivers are a dime a dozen.
