look up any word, like sex:
An infectious disease brought on by the all-powerful, often soul-consuming addiction to the dirty, raunchy, dark beats and heavy bass lines of dubstep.

Common symptoms of the dub bug include but are not limited to: bassface, involuntary head bobbing, the urge to take part in glowsticking and like pastimes, and of course, the despicable sensation of full-on frontal face meltage. If the condition persists, it may result in a permanent state of BASSFACE.
My face is all scrunched from the bassface, man... I got that dub bug.
