A preemptive flush occurs when one is sitting on the shitter, hears footsteps and flushes even if it isn't neccessary in order to let the person whose footsteps you heard know it's occupied, to deter them from coming into the toilet while you're doing your business.
A: I was sitting on the toilet mid-shit when I heard my sister's footsteps, I did a preemptive flush so she wouldn't come in while I was doing a blumpkin.

Get the Preemptive Flushmug. When a man, to prevent himself from sleeping with a women he would like to sleep with but would regret sleeping with, wanks one off to release the urge to sleep with her.
I wanted to sleep to sleep with Rachel but I knew it would cause a lot of problems so I went for a preemptive stroke instead.
