slicker than cum on a gold tooth 

The slickest of all road conditions. Approximately five times slicker than snot, four times slicker than snot on a door knob, three times slicker than owl shit, and twice as slick as greased owl shit.

I asked George how slick the roads were and he said they were slicker than cum on a gold tooth, so I stayed home.
