Paying out the ass

Paying Dimes 

Constipation.

From the Latin, "Here I Sit Broken Hearted, Paid A Dime and Only Farted".

"Man, you'd think after the three bowls of chili I'd be able to lay some cable, but I was just paying dimes."

paying homage to the porcelain goddess 

The ritual of getting on one's knees and discharging the smelly contents of the stomach into the toilet.

I was paying much homage to the porcelain goddess this morning because I drank too much of the Beast.

Paying it Forward

The act of responding to a good deed with another, hence, "One good turn deserves another".

The other definitions I've found on this phrase are OK save for the grammar errors, but I'm paying it forward with this easier to digest version.

Paying the Dark Price 

Shitting your pants.

Dude 1: Hey man thanks for covering my shift while I needed to go to the bathroom.
Dude 2: No problem.
Dude 1: Yeah man if it wasn't for you I would have been paying the dark price and paying for a new pair of jeans too.
