Frozen Mitten
Originating in Minnesota, it is when a male jacks off into a mitten and puts the mitten outside so it can freeze overnight. This is in preparation for having a mate over the next night. The cum-filled mitten should be frozen by the time your mate comes over, and it is then used to spank your mate.
Friend 1: Prepare a frozen mitten before your lady comes over for sexy time, don't ya know!
Friend 2: You betcha!
