Dub step rammus
Imagine a rammus skin where your Q did the dub step build of quater notes, to eighth notes, to sixteenth notes. Your W covered rammus in a coat of sound waves like you would see on a sound recording program. Your E would shout out a "Pre - bass drop line" to taunt enemies. your ult could have a different "rave esc" flashing color pattern while playing some kind of dub step while active to really show how hard rammus drops the bass.
