Brooooooh that slut let me swim upstream last night. Water was a little muddy though if you know what I mean.

Upstreaming 

The act of walking quickly towards an approaching taxi cab so as to hail and enter it before someone else who is obviously waiting nearby for the same taxi.

Larry: What you upstream me?
Upstreaming Lady: Everybody upstreams you idiot, you don't just stand there like a jackass.
Larry: That's anarchy we need some rules!
Upstreaming Lady: Whatever! (flips the bird as cab drives away)

shitting upstream

In literal terms, it is the act of defecating against the current of a body of water because the circumstances of the situation offer the individual no other option but to poop right then and there in the river. This messy situation, having to poop while submerged in water, is exacerbated by the poor choice of the individual to defecate with his/her backside facing upstream. The current then pushes the feces back in the direction of the defecator and thus makes this already messy situation much messier. In an everyday scenario, this expression means to attempt to improve a desperate situation but in doing so, make the situation worse for oneself.

Example:

Dude 1: How’d it go with Kelly last night? You finally get to bone her before you left for school?
Dude 2: No, I made it worse.
Dude 1: How?
Dude 2: Got myself into the friend zone. I heard she was more into sensitive guys so I tried really hard to be sensitive around her. She ended up telling me I'm a really good person and we should just be friends. I was shitting upstream, man. Now there’s no chance we’re gonna bone, even when we come home for winter vacation.

Upstream Tristo 

The words Upstream Tristo typically describes someone's penis to be microscopic and physically cannot grow any bigger then 1 Nanometer in length.

Person 1: Omg Jenifer said that when Tristan took off his clothes just before they were about to have sex, she couldn't see his penis! She even held a magnifying glass to it and still couldn't see his penis. It was an Upstream Tristo size!
Person 2: What a fucking loser!

upstream 

The developers associated with a software project, usually an open source application.

The idea is that software streams from developers, to package maintainers and then to users. When reporting a bug "upstream", it's reported from users to maintainers/developers or from maintainers to developers.

"Please report this bug upstream."

"Wonder what upstream has to say about this."

"Silly upstream, that bug has been ignored for 42 years now"

"Thank you upstream, for doing this in your spare time"
