I busted out the Power Flush on your sister last night. I hope she doesn't get an infection.

When you flush the toilet and attempt to "power shit" in the few seconds of loud flushing noise. One dose this in hopes of not being heard taking the shit. This often happens with those in newer relationships or when one cannot avoid answering natures call in a public restroom.
I didn't think the anyone was home so when I heard a voice, I had to"Power-Flush"
