Drinking a great amount of alcohol in a minimum amount of time.
Tonight's gonna be pressure tanking with the guys!

I do wanna get wasted, let's hit the all you can drink bar and do pressure tanking!

Let's pressure tank tonight!

Dear lord, I have a bloody hungover! Must be because of the pressure tanking in the 2£ bar last night!
