Musket blast 

Best described as the unmistakable first blast of a large bowel movement that reverberates through the thin bathroom walls of a cheap motel. This foul deed is often accompanied by giggles and/or disapproving comments depending upon the age and gender of the audience.

While deep in the middle of an Adult Swim marathon, the three young gentlemen watching the show were both humored and amazed by the incredible musket blast that came from the adjoining bathroom and literally shook their sleeping quarters to the core.
