Grenade Pin 

When a girl has her period and you still want to go down on her, leaving the tampon in moving the string out of the way. Once things heat up and it's time to finish her off, you grab the string with your teeth and pull it out whipping it across the room in one motion.

I didn't care that she was on her period and neither did she. I wanted to go down on her. The only part that startled her was when I pulled the grenade pin.

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.
