Brown Streak 

A brown streak is when you pound your lady in the ass and you whip out your dick. You slide it down her back resembling a brown streak.

Man, I fucked that beezy in the ass and left her with a brown streak.. Markin' my territory!!

brown streamer 

From military parachuting: when a parachute fails to open it's called a streamer, and if the jumper's reserve parachute doesn't function, the jumper's going to die- the brown in the phrase is either from the dried blood on the chute when the jumper assumes the consistency of rasberry jam, or from the well-known, first you say it, then you do it..."Oh, sh--!"

I thought sure that streamer was going to be a brown streamer until his reserve popped at the last second.

Brown Streaming 

When you're in a bath full of hot chocolate and need a wee, but carry on drinking it, then weeing lover and over again.

"Hey dude, what are you doing today? I'm staying home and brown streaming"

Any smudged turd not on the inside of a toilet.
