Insinuating that someone will quiet someone else by placing their penis into the annoying, talking persons mouth.

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!

A Type of weapon attachment that redirects propellant gases to counter recoil and unwanted muzzle rise to help with accuracy while shooting
The muzzle brakers I bought were pretty helpful by decreasing the recoil of my weapon and helping me aim better.
