Back-nine 

When you get little sleep at a friend's house/wherever you passed out, head home, and get the rest of the sleep you need to get a full night's rest; a non-contingent nine hours of sleep.

John: Wow, three hours of sleep at this party? I had better head home to get the back-nine.

Playing The back nine

The act of engaging, after a solid regimen of vaginal sex, in the act of anal sex; also known as sodomy. One can also hop onto the back nine right away if possible. This phrase is a simile derived from the game of golf when one plays the last nine holes on an 18 hole golf course.

Me and my girlfriend were having great sex last night when all of a sudden we tried to switch it up and ended up "playing the back nine" wink* wink*.

LUNCHY BACK NINE 

Fat, Thick or Full Butt, Backside or Arsze, most often female. I originally heard this saying from a young male work colleague ('Milky') (Police Officer) when he was describing the physical appearance of a female.

When referring to a female's butt. "She has a Lunchy Back Nine" means it is a bit full and thick like the thickness of grass on the back nine holes of a golf course.

The Back Nine 

A golf course that takes forever to complete.

I hate the back nine. 2.0 cogs galore, mazes that make no sense, and lots of bugs.
