The most stupid synonym for dubstep that people who just got introduced by the music use.
It originates from the sounds that are contained by the known 'wobble' that mostly starts after a 'drop' of a dubstep song
Me: Hey man, do you like hip-hop?
Other: No I like dubstep!
Me: Why do you like it?
Other: CUZ OF THE WOB WOB WOB WOB
Me: You know any good dubstep?
Other: Oh not really, I just like the WOB WOB!!!
