When a male and female are getting intimate and the girl is giving the guy a hippity handjob. Then the female, without the male's knowlege, hops on top for a slippery suprise, often making a slide whistle noise.
Hey guys, that bitch just gave me a Slippery Whistle!

I was shocked when that girl gave me a Slippery Whistle in bed!
