An MSN stain is due to a raunchy MSN conversation that ends up with the guy beating off in such a hurry that he only unzips his pants and immediately starts wanking. MSN stains are usually found on the pant leg and surrounding the zipper. Stains can also be found on t-shirts if the said person was unable to hold his bunched-up shirt under his chin long enough.
