Grandma's Mud Castle 

After having dined at Grandma's Kitchen an involuntary purge of the lower intestines resulting in a contained explosion within your pants. Once in bathroom, the removal of your pants causes the feces to spill over the front of the porcelain throne creating a mud mound on the floor and leaving the door open for all to see!

I hate my in-laws so much I created a Grandma's Mud Castle for them!

Traveler’s Mud 

Diarrhea brought about by one’s experience traveling. Often times traveler’s mud occurs as a result of one’s voyage on a long flight.

My farts have been insane ever since I got back. I think I have a lingering case of traveler’s mud

if there's blood, play in the mud

when a woman won't let you have sex with her because she is on her period or when you don't want period blood all over your penis, you have anal sex instead.

Guy: "let me smash that vag"
Girl: "I would let you, but i'm on my period"
Guy: "if there's blood, play in the mud !!!!!"
