What is Grenade Pin?
1.
a used tampon that is hidden so it will smell up the room.
Sally was fighting with her boyfriend for the final time. She could no longer handle the fact that he liked to watch Mr. Rogers during lovemaking. Right after they had sex she told him it was over and proceeded to leave a grenade pin under his pillow so that he would find it weeks later. Or soonder depending upon the smell factor.
