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!

Term used to refer to the late-model NES. Games are inserted into the top and stick out from it, similar to a SNES or Genesis. Contrast this with the original side loader model, where the games did not stick out and were covered by an opening/closing flap. Also adopted a different controller style from the side-loading NES, the shape of which earned it the nickname "dog bone"; this controller is widely considered inferior to the previous square controller. Top loaders can be easily found on eBay at somewhat exorbitant prices.
Top loaders are fine and all, but nothing says "Nintendo" like that chunky old side loader.
