Pißwasser (mispronounced in-game as "pisswasser"; the correct pronunciation is actually "pissvasser") is a fictional German export lager frequently advertised in Grand Theft Auto IV and Grand Theft Auto V. 'Wasser' in the beer's name translates into English as 'water', making the beverage's literal name 'piss water', which is a slang term for cheap, watered-down beer. Billboards seen in-game expand the urine references, even going so far as to suggest the bottles contain nothing but urine (perhaps in reference to the urine in Corona beer rumor). Furthermore, the television ad has labeled the brand with the words 'Ü-Rhine', which is probably also a nod to the Rhine river in Germany (also a pun on "urine"). The labels on the bottles are similar to Grafenwalder's labeling. The beer's slogan is "You're In, For A Good Time", once again playing to the urine theme.

The radio and TV advertisements for the beer feature variations of a song sung by a stereotypical redneck man with lyrics that portray comically exaggerated effects of alcoholism, including "giving a dude head" and "driving drunk off a pier". A pack of Pißwasser costs 6 dollars at 24/7.

Some webmasters have received a six-crate Pißwasser from Rockstar[1], one notably to UK website ComputerAndVideoGames.com[2].
