Mud Thunder
Slang for a case of diearhea.
Wow Marie, all that Mexican food gave me a bad case of mud thunder.
Thunder Mud
This is the shit you take next morning after a glorious diner accompanied by 5-6 beers. Starts with cramping along with a euphoric feeling. As you sit a little push causes the heavens in your colon to unleash its fury. The consistency of fecal matter is that of mud or wet concrete. The flatulence is loud and non stop until it starts to fade off. You are exhausted after the episode.
Get the fuck out the way! Im going to blow the toilet out with all the fury of thunder mud.
