Brown Panther 

A sneaky poo that surprises you out of nowhere, often in critical situations.

"Dude I heard you struck out with Melissa! What happened?"
"Well we got back to her place, I was just about to seal the deal when the Brown Panther struck!"
"Oh shit!"

The weightlifter was about to win the gold when the Brown Panther struck!

Brownback

Wiping your dick on your partners back after anal intercourse, usually to get rid of the santorum, results in Brownback.

Named after Governor Sam Brownback (R-KS)

Mike is so kinky! He asked me to give him Brownback last night!

browner pastures

A place less desirable than your current location. The opposite of greener pastures.

I can't believe Fred left this amazing city for browner pastures.

Brown Marker 

A shit that, no matter how many wipes, will leave a nice brown streak on every piece of toilet paper used in an effort to clean your stinky asshole

I've been sitting on the toilet for 10 minutes trying to wipe my ass but I have a damn brown marker!

Brown Sweater 

A girl with an extremely hairy, almost bushy if you will, anal region. The old brown eye could use with a serious waxing.

Braaaaahh I had that ass up and was about it hit it and looked down at a brown sweater. Had to weed through the brush to get in there.

Brown-Eye Gazing 

When you stare into the gaping abyss of someone's rectum.

Fleece Johnson's (aka The Booty Warrior) lust for Little Tony was so great he decided to forgo the customary foreplay of brown-eye gazing, and thrust deep inside, deep 'n' wide.
