Peeing down the leg of your suit would work as long as you could maintain the output/stream... But it would collect in bottom of your boot and cause you to both stop and have stinky/wet piggies... ;^)

It would move your center of gravity by zero.
If you piss 0.5 kg (that's a two cup piss man) and you weigh 100 KG (with suit an all), and you shift the piss weitght by 1 meter, your body would move 1/200th of a meter, or 0,5 cm. Your center of gravity remains unaffected. Then end velocity after the piss lands into the boot would be ZERO. Action-reaction would propell you while the piss flies, but the piss hitting your boot would bring your CG back to point zero.
I'd rather die not in my own piss. Personnal choice, only personnal choice.

Rapid throwing motion does not work for after the throwing, a force is exerted upon your body to STOP your arm.
There are violation of action-reaction law, but they are not recognized by mainstream physics. And they don't happen with linear motion. They require transfer between variable speed rotational movement and linear movement. It is alledgedly produced by compounded multirotational-linear movement.
There are patents and claims of inertial thrusters that eject no mass.
Nasa is apparently working on one.
A fantastic source of info for that is Infinite Energy Magazine.
Google it and you'll hit right on it.
Have fun !
IMO, the best way to get out of it would be to puncture a cooling fluid line (providing you have your Space Swiss Penknife handy) . It would get ejected at the suit pressure, and have more weight than the gas. Gas has higher theoretical yield, but in that case, since you probably don,t carry a large mass of gas, I think it better to eject coolant (but not all of it unless you want to turn into a half-frozen half sizzling barbecue.
