noun: Any dubstep track that evokes the mental image of slugs bobbing their eye stalks to the music, usually brought about by strange sounds in the song.
Note: Not to be confused with "slugging"; the act of dancing to slugstep by walking around rhythmically. (Like a slug.)
Man, have you heard 'Take Time' by Kromestar? Weird noises. Sounds like some straight-up slugstep.
