The coital act of a penis pounding a forgotten tampon deep into the female vagina.
I had no idea I was loading the musket. That whore! The ensuing infection will surly cost her!

Another name for Kids in Sandbox, the sexual practice of ramming a foreign object into a man's penis for sexual pleasure. Named so for the way a musket is loaded by ramming the shot and gunpowder down the barrel, before rifles and magazines came into play.
"Even thinking of that video of the chick loading the musket makes my penis sad."
