Mud Oven 

Like a Dutch Oven, but rather than fart, you shit.

"Sometimes you can't always trust a fart, and this time, rather than going Dutch, I gave her the ole Mud Oven."

Mexican Mud Oven 

Similar to a Dutch Oven. While your partner is in bed with you, and their head is under the covers, you flatulate and a little extra surprise escapes.
