Getting in the piss 

One of the highest ranks of expressing how intoxicated you are, or will be. More aggressive form of 'getting on the piss' or 'OTP', as you are quantifying how deep you will be getting in the piss, rather than just getting on it. (See also: piss = alcohol/alcoholic beverage).

John: What are ya up to tonight mate?
Darryl: Getting in the piss bro.
John: How deep?
Darryl: Till I can't feel my legs

Taking the piss 

To make someone who's trying to seem important less important. Derives from the piss-boner men wake up with in the morning, it's a fake boner. If you took the piss away, there would be no boner. Do you see?

That's the original meaning, however taking the piss now means just giving someone a ribbing and in the most part not meaning to be malicious.

Original meaning:

Guy 1: "Hey guys, what do you think to my awesome new haircut?"

Guy 2: "I think you look like a fucking prick, mate...you look like a real slob".

Other guys: "Haha, Guy 2 really took the piss out of guy 1!"

Meaning as it is now:

Guy 1: "Man, I only got a 45 on my last assignment"

Guy 2: "Haha that's fucking shit!"

Guy 1: "Don't be so mean"

Guy 2: "Cheer up man, I was only taking the piss"
