Similar to the Tennessee Muzzleloader, the Millennial Musket-loader involves an liberal vaping art student engaging in doggy-style sex with a female. While having sex, the male pulls his penis out and places a couple drips of his favorite vape juice on the woman's asshole, and proceeds to shove the vape juice into her body with his penis essentially "loading the musket". If a juice with high nicotine content is used, both participants can expect to experience a significant nicotine buzz.
I was banging some girl from the local vape shop last night, and she let me give her the millennial musket-loader.

An absolute wretched act where one is having safe, consensual sex with their friend’s mother, but proceeds to shave their pubes and insert them inside of her vagina whilst thrusting upon her. (Side effects may include) rug burn, hair in your urethra, ball entanglement, pubic nesting, bird chirping.
Figure 1: “I’m gonna give your mom the good ol’ Louisiana Musket Loader.”
Figure 2: “I don’t even know what that is.”

When you are making love to your girl and you sneak a high dip of Skoal Long Cut in your mouth. You then bend her love and after about 5 pumps, pull out and put the tobacco on the end of your winner and pack that in tight. "Like packing a Musket"

When you take a ZYN, tear it open, and pour it down your urethra stamping it down like loading a musket.

When you’re fucking a girl in the ass:
1 pull your dick out
2 take the dip out of your mouth
3 put it in the asshole
4 put your dick back in stuffing it into the anus
