The word "MotherShitter" is a rarely used cuss word which actually has quite the amount of baring in a non-lethal verbal assault.

The meaning of such a word can be best defined by a "shitter of mothers...." A person who's bowel movements have the capability of produce a mother from time to time.
"Wow John....I seem to have misplaced my mother...I can't seem to find her anywhere!!"

"O Timmy....You've lost your mother?"

"Yes John i do believe i have"

"Well Timmy....PPPBHHBHHHBHHH....."

"O golly Gee John...A new mother!?!?! For me!?!?!'

"Yes indeed Timmy.....The uncertain movements of my bowel have just produced for you a brand new mother to love and care for"

"Shuks John...Your such a lil' MotherShitter!!"
