Get the Brown Fluffmug. When you go to your local super market and buy that delicious stuff they cal Fluff that you mix with Peanut Butter. You than go home find your girlfriend and say "Hey Babe, Let me put some Fluff on Your Muff." Than you kick it wit her and watch her legs spread as she begs you to spread the Fluff.
