bolt out of the brown 

1) A completely out-of-context shitty thing to do or say, especially from an unexpected source. From the elderly phrase "bolt out of the blue", but modified with skidmarks for flavor.

2) (driving) Some asshole coming from out of nowhere to bust your chops (cut you off, tailgate and honk, etc.)

1) Our night out was pretty bangin' until Chess Club Bill dropped that ear-splitting N-bomb at the bar. What a bolt out of the brown!

2) Jesus! Where did this pissed-off horn-addicted Excursion-driving dickhead getting all up my tailpipe materialize from? This fat bastard was a bolt out of the brown!

Get your brown outta town

An expression used to exclaim the desire for someone to get their shit outta there, metaphorically and literally.

That fucker Ryan shat his pants in homeroom, so I told him, "Get your brown outta town."

Think Outside the Brain 

A wittier version of the non-innovative cliché "think outside of the box". This sarcastic phrase should not be confused with other idioms such as "use your intuition", "go with your gut", or "process sensory data with your spinal grey matter".

Boss: If you can't think outside the box you'll be downsized.
Employee: Will I get your job if I think outside the brain?
