piss-on 

The act of getting intentionally obliterated by alcohol in pursuit of a good time. More thorough than "going out for drinks" - you know damned well you won't be driving home from a proper piss-on.

Girl: "Why did Larry just drop his keys in the fish tank?"

Guy: "He's been looking forward to this party all week - he pegged it as a piss-on on Wednesday!"
