A studded condom. In the south, "mud grips" is a term for truck tires that are designed for driving in the mud. Since sticking it in the butt is also called "playing in the mud", this term is also commonly applied to studded condoms.
After picking up this slut from the bar, i stopped at the 7-11 and bought a couple mud grips for later.
