When two males dock one another, but one begins to urinate with great force into the other's urethra.

It's called salmoning because it is much like a salmon travelling up stream; it is also known also as up-streaming.
As Jeff was docking Dave, he realized he needed to take a piss. "Just salmon me, baby." Dave said.

"Oh man, I love salmoning guys."
