mudderboat

The act of taking a shit on a woman's chest, then pushing one's face in between the shit covered ample breasts, and rocking one's head side to side while making a rapid lip moving motorboat engine sound.

Similar to a motorboat with the addition of the feces.

Did you motorboat that girl with the big tits?
No man, I had the runs so I did a mudderboat instead!

Murderboating 

The act of motorboating a woman's large cleavage and then getting choked (possibly to death) by said cleavage.

"You want to bury your face between my tits?"
"Sure, as long as you're not murderboating me"

"Hey have you seen Kyle lately?"
"Haven't you heard? He got murderboated last week!"
