The sex act, when you are having sex with a partner, in a doggy style position (or bent over in a downward dog position). The giver is about to explode his load, but will pull out and ejaculate on the lower back of his/her partner creating what appears to be a glacier.
Man, my date last night asked to give it to her doggy style. I decided to go with glacier forming and not cum inside her.
