It's when you are getting a girl from behind or doggie style and you take a breathmint, and put it in your anus. Then you take out the breathmint and put it through your pubes, and then after you are done having sex, you tell her that her breath stinks and that she needs a breathmint, and give her the Harry Rumplemint.
That chick I was banging last night was so hot, but her breath stunk like Suttin, so I gave her the Harry Rumplemint.
