look up any word, like thot:
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.
Wow Michael, I'm literally buzzing my ass off! That was so much better than last time you gave me the Grizzly Muzzle loader!
