"Piss" is a term long used in the UK and more recently in Australia for (generally weak) alcoholic beverages. Pissing the night away is an idiom that means drinking alcoholic beverages all night. It has nothing to do with urinating, as one would assume in the United States.
My friends and I spend our weekends pissing the night away.
