There's been a bad day at the office, an extra-festive party or so on — a character needs a freaking coffee or a drink. A popular visual gag is to have the character drink from a really big cup. The Gigantic Gulp is any drink that comes in a ridiculously large cup, barrel or bucket, usually with its size grossly exaggerated for comic effect. (Possibly even larger than the machine that dispenses the beverage, if a convenience store or similar place is involved, making it physically impossible.)
Often used in conjunction with the Potty Emergency and Potty Dance tropes; bonus points if the character feeds the liquid directly into his system with an IV tube. For extra irony, make it a diet drink.
Also see Must Have Caffeine, I Need a Freaking Drink, and Cup Holders for related tropes.
Not to be confused with Loud Gulp, which is what bystanders seeing a Gigantic Gulp might emit...

In one episode of Star Trek: Deep Space Nine, Dr. Bashir mentions that he is feeling tense, so Quark begins to make a "Warp Core Breach", which is a multicolored, bubbling, smoking drink served in a fishbowl. Quark promised that after one sip, the doctor would be relaxed for the next three days.

The episode "The Vacation" of Chowder featured one of these - Mung asks Chowder if he's ready to head off to the beach. Chowder says he will be just as soon as he finishes his bottomless soda. It was your average sized soda cup, but it was very long. He just continued to pull an endlessly long cup out of Hyperspace until Mung got fed up with the joke.

Similarly, a chetvert (an old Russian style vodka bottle, literally translated as "quarter", as in one quarter of a bucket) holds three liters of the stuff, equal to six normal vodka bottles.

The website Vat19 sells a glass capable of holding a six-pack of beer. Also available is a glass that can hold an entire bottle of wine (5 glasses will empty a standard box of wine in one go).
California's Stone Brewing Company is most famous for producing the "Arrogant Bastard Ale", an extremely hoppy American Strong Ale that basically caters to all of the things American beer snobs love (including high alcohol content, intense hoppiness, and dark, rich color and flavor) and everyone else hates (hence the name). Although Arrogant Bastard comes in standard beer sizes, it also a 3-liter bottle of beer that is so big, the company had to invent their own manufacturing machines and complete the bottling process by hand.
A pizzeria in Baltimore's Inner Harbor food court had this as a gimmick. You could buy a 1-gallon soda (which was basically a small bucket with a straw through the lid) and advertised free refills. By all accounts, a large portion of their business was tourists stopping in for their novelty bucket of soda.
New York City Mayor Mike Bloomberg quite infamously attempted to defy this trope and ban sodas larger than 16 ounces, viewing them as a public health problem and a contributor to obesity. The law was struck down by the courts... but not before getting mercilessly mocked by Jon Stewart and various blogs.
The Hardees/Carl Jr's fast food chain have made a habit of super-sizing their drink sizes by default for years. What is considered a Regular drink size to them is what nearly every other fast food chain in the industry considers a Large. What they consider a large.. well the drink straw only sticks 1/8 of an inch out of the cup lid when you slide it all the way to the bottom.
