Drink to the Future is a drinking bar. To get this bar you must watch all three films in the Back to the Future trilogy back to back. Everytime someone says "Doc", "Great Scott!", or "Back to the Future", take a drink from your alcohol of choice (beer, mixed drink etc.)
This is interpreted as Marty McFly saying "Doc" in reference to Doc Brown, but also includes any other character saying Doc or Doctor in reference to Doc Brown.
This is anytime a character says the phrase "Great Scott!".
Back to the FutureEdit
This is anytime a character says the phrase "Back to the Future".
If someone vomits during the attempt they are disqualified. Missing a drink without making it up also produces the same result.
