look up any word, like bae:
 
1.
Australian slang; defines heavy intoxication through alcohol consumption. Other descriptions could be wreckless, pissed, drunken, wrecked, smashed, fucked. Find someone pisswrecked at a piss-up. Typically characterised by staggering around, slurred words...etc.
Some random: "The other night was a prooty well-sick piss-up."
Me: "Yeah I got well pisswrecked!"
