Here's a wee yarn I used 25 years back, in NZ, to take the piss out of (make fun of) Americans' use of the term "I'm pissed" (annoyed) - If I was "pissed" I was drunk._________________________
It was pissing-down (raining hard), and I was pissed-off (annoyed), so I pissed-off (went) to the pisser (pub) to get on the piss (have a drink). I was pissing-up-large (drinking a lot), so pissed-off to the pisser (toilet, dunny, dyke, shithouse, outhouse, long-drop, crapper, etc NOT bathroom - that's where you have a bath) for a piss (leak, slash, etc) in the piss-tin (urinal).
The piss (beer) was getting to me, and I got as pissed as a parrot [newt, chook etc] (very drunk). I went on to a piss up (party). And....
Wheww...
This old piss-pot (drunkard) was piss-crook (hungover) in the morning.
Stop pissing yourself (laughing) and piss-off (go away) - it wasn't funny!
Cheers - Sam
