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!

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.
Mike: Did she projectile vomit?
Dan: Hell yeah!
Mike: Nice!
Mike: Did she projectile vomit?

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.

The act of having vaginal/anal sex with a partner and using your semi-erect penis (ram rod) to shove your testicles (ammunition) in the desired orpheus (muzzle) like that of a muzzle loading rifle. (Once your testicles are in the desired hole, you may also put your penis in the unoccupied hole if you so wish.)
"Bro! Last night I totally gave this haggard chick the Muzzle Loader in my car! I wasn't shooting blanks either!
