whack-a-molin' 

When you have really got to take a shit, and every time it starts peeking out, you have to scrunch up your butt-cheeks and push it back in. So your ass resembles a whack-a-mole game with only one mole (built for the special kids with really bad reflexes).

Dude, I was whack-a-molin' so bad last night I thought I was going to have a Vasovagal episode! I was lucky the Browns even made it to the Superbowl.

whack-a-moling

When one is needing a turd SO bad that the turd is protruding from the sphincter and retracting at a constant rate, thus giving the faeces the appearance of a "whack-a-mole."

"Oh man I need to get out this car, I'm Whack-a-moling!!!"

"Sorry I am late boss. The stairs were a nightmare with this whack-a-mole in my arse."

wack-a-moling 

The act of pushing a fecal loaf out of one's anus and having one's partner try to push it back in with hand or tongue for sexual pleasure.

I had the greatest first date last night. We went to a lovely dinner and then had drinks before going back to her place for wack-a-moling and a night cap.
