The act of masturbation, usually taking place while at work, while driving, in an airplane bathroom, or some equally inappropriate place. The sudden onset of this need is most often brought about by some form of visual stimulation, such as the close proximity of some serious talent. Running batch nearly always results in the deposition of a large load on one's work desk, steering wheel, airplane bathroom door, or some equally undesirable location, leaving the sweaty participant to ineffectually clean up the mess with whatever happens to be on hand.
Man, I was sitting next to the hottest chick on the plane last night. I couldn't even wait until I got back to my hotel, I had to run batch right there in the airplane toilet!!
