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.

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*.

Hey Suzy, put down that fucking iphone and bend over so I can play the back nine.

Who cares if you're on the rag? I'll just play the back nine.

Play the back nine. 

Fuck a slut ass cunt whore in her ass.

After I busted in her stank ass pussy, I said bitch turn over, then I played the back nine.

Cheeks 

An Irish phrase meaning shit, derived from ass
(Not to be confused with the literal description of one's buttocks)

"Did you hear the song Aylek$ dropped?"
"Hardly. Her music is absolute cheeks."

"My boyfriend say LaFlame is cheeks."
"Tell your boyfriend I said it's his mixtape that's cheeks."
