Another term for anal sex. In the baseball analogy, where home is classified as vaginal sex, third is oral sex, etc., there is an absence of anal in most accepted versions. Charging the mound is an accepted term.
Man 1: Get this, I was charging the mound with that girl last night!
Man 2: She let you do anal?!? You lucky bastard.
