Clock Butt

When one twerks their ass in a rhythmic fashion. Used like a metronome to keep musical timing.

I was having trouble keeping time whilst playing the piano so I hollered to my bitch "Yo girl, gimme some clock butt".

Clock butt

A butt so fine you can tell time by looking at it.

Damn girl, show me that clock butt!
I need a clock butt to find out if i'm late for the meeting.
