When you are doing a chick in the ass, right after you pull out her anus is still expanded and you insert your dip into her anus then stick your dick in and continue. Hence you are loading the muzzle.
The vile (or pleasant) act of defecating into your mate's mouth and proceeding to force the excrement down his/her throat with your penis. Your mate's mouth acts as the muzzle, the exrement acts as the bullet/gunpowder, and your penis acts as the ramrod. Hopefully your mate will projectile vomit immediately after being muzzle-loaded, so as to replicate the firing of the loaded firearm. If you wish to take it a step further, you can hire a Civil War Commander reenactor to shout out commands during the process such as "Prime!" "Draw Ramrods!" "Ram down the cartridge!" and "Fire!"
Dan: Bro, I hired a Civil War Commander reenactor to shout out the proper commands as I performed the muzzle-loader on your mother last Thursday.
Ok once you are fucking a girl from behind stop, pull out, pop a copenhegen out of your mouth, place it on the rim of her ass and........load the muzzle!
During gay sex, one man takes a shit in the other mans anus. (see alabama hot pocket) The man who took a shit then fucks the other man in the anus. The man who was fucked in the anus then expels the packed-in feces out of his anus, creating the effect of a muzzle loader rifle.
When one partner takes a dip (chew) out of their mouth, put it on their finger and shove it in the others anal cavity. After this takes place fornicating insues.
When having intercourse in "doggy style" you extract the smokeless tobacco or dip from you mouth and place it into the girls anus. Then using your penis, you ram it into her anal cavity.
Pioneered in the great state of Alabama, the Birmingham muzzle loader occurs while chewing tobacco and having anal sex simultaneously. One removes the ball of tobacco from his mouth, sticks it in the anus of the girl, and rams it in with his penis. The Birmingham muzzle loader ladies and gentleman.
