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!!

A tradition seen in New Zealand high schools where at the end of the year, students strip down to their underwear and run across their school grounds (or another school)
Person 1 - "Did you hear? Steve went to the grundy run yesterday!"
Person 2 - "No shit Sherlock, like two thirds of the school went."

That unfortunate time when you just don't have a tampon. A reference to Kiran Gandi, who ran the London Marathon without a tampon to make a statement for women without access to sanitary products.
I got my period and realized I was totally out of tampons so I had to run a bleeder over to Walgreens.

The beer shits you get after a long night of drinking the greatest beer on the market, Rolling Rock premium beer. Much like the bottle, it has a definitive green color to it, and, like the beer shits you get from drinking bud light, it comes in waves of 2 to 3, maybe 4 trips to the bathroom. However, Rolling Runs has minimal/no odor, and that's a plus.
