Essentially, it's when your bangin a girl/man from behind with a dip in (preferably grizzly wintergreen). At the discretion of the banger, take the dip out and shove it in the girl/guys anus. Next shove your dick in the ass, thus muzzle loading. If done correctly, the bangee should receive a buzz via the inferior rectal branch of the pudendal artery.
