Fancy Way: Usually, a ridiculously simple disagreement between two or more people under the intoxicating effects of alchohol, that is quicky changed into a brawl. The reasons may vary, but anything can be offensive to an alchohl impaired mind. These fights will more often than not take place in a bar, pub, club, or any public facility that offers alcholic beverages. In any case, anyone involved in the brawl may be immediatly thrown out of the premises by bouncers, and will 1) continue the fight, or 2) forget what happened and attempt to limp home.
Sucka' Way: When two drunk dudes get pissed at each other for some bull shit over sports, get up, or a chicken wing. They'll try to knock each other out, but will probably get the shit kicked out of them by some guy who's bigger and more sober than they are. They can be entertaining to watch, depending on who's fighting, which bar it is, and whether the Raiders or the Steelers won the game.
Jack: *moan* What the hell happened last night? Ow...
Mac: Shit, you don't remember? You got in a bar fight with some fucker who's a mixed martial artist or some shit. Man, you were so fucking drunk, your head was spinning BEFORE he hook'd ya'!
