Murray cod

To go on the nod, be it from heroin or another drug.

Jeff had a hit of heroin and now he's gone on the Murray cod.

Murray cod fishhook

The act of fucking a girl doggy style & throwing a line over her head to fishhook her head back so she’s looking at you with those big fish eyes.

My girlfriend really wanted to go fishing, but I only had one rod. Luckily I gave her a Murray cod fishhook, that sorted her right out.
