The author of the webcomic Manly Guys Doing Manly Things once said she imagines the main character Commander Badass D37-9E-B52 "Rock Lobster" sounds like some actor I can't remember gargling hot tar and chunks of glass.

And considering it's confirmed in-universe that he can survive a 15 round magazine to the temple (as can any of his nonspecific space-future space-marine clone siblings) gargling tar and glass would be like ordinary mouthwash for him.
