similar to being on the piss but more fun if you can hold ur poison. most commonly done after work or on weekedns where you head down to your local and drink till your your best mate looks like elle mcpherson
most derocunts in sydney can't hold their piss and start riots making the rest of australia look bad when really their just cunts who ruin it for everyone
"Im gunna go hit the piss"
"cool mate, are you man enough the stay all night though?"
"yeah mate not like those dero cunts in cronulla, wankers they are"
