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)

Upstreaming 

Upstreaming (V.): When one fills the asshole of their partner with water then fucks the water out of said asshole.

Sure white water rafting is cool but you ever try upstreaming?

I used to date someone who was into upstreaming. That shit can change your life.
