A severe case of the shits that, upon exit, resembles the sound of a shotgun being fired out of your ass. Usually caused by eating 4 or more dollar menu sandwiches in one sitting from including, but not limited to, McDonalds.
"Ughh I have the McShotguns today."
"What did you do? Eat two McChickens last night?"
"I don't have the McShits."
"Two McChickens and a McDouble??"
"Not the McSplatters either."
"You couldn't possibly have eaten..."
"The McShotguns dude."
