gabber
A derivitive of a Yiddish word meaning "friend", a gabber is a person who likes hardcore techno originating out of Rotterdam that goes by the same name. The name was coined supposedly when a club bouncer stopped someone, saying "Gabber, you can't come in here." Gabber can be used widely however, such as for a substitute for "dude" or "brother". Gabbers are also often mistakingly confused with neo-Nazis because they sometimes have shaven heads and wear black leather.
Example:
Gabber, get in the car.
Pump some of that gabber music!
Those gabbers are dancing like crazy!
