jammin like salmon 

When someone is having such a good time (i.e. drinking, dancing, etc.) that the only way he/she can describe it is with rhyme; a derivative of the nonsensical "out like trout"

Mary: "How was the party last night?"
Brad: "It was so much fun. We were jammin like salmon until the cops came. And then we were out like trout."

Jersey Slamma-Jamma 

This takes preparation. You need to be on the verge of a constipated poop. In other words, a solid shit. While performing anal, doggy style, you stealthily shit in your hand. In one fluid motion, you pull your cock out and slam the shit in the gaping hole, and immediately JAM your cock back in.

I haven't shit in a week, I'm going to give her a great Jersey Slamma-Jamma.
