A sport similar in origin to Rugby. As an American, I've played both, and they're both good sports. Football is a complicated game, but here are some examples of rules:

11 men on the field at a time (on offense, you need at least 7 people on the line of scrimmage, and a Quarterback to receive the snap to start every play).
Players on offense are broken down into many positions, the main ones are Quarterback, Running back, Full back, Wide Receiver, Tight End, Tackle, Guard, Center.
Players on defense are broken down into 3 levels, Linemen, Linebackers, Defensive Backs. Lineman normally consist of Ends and Tackles. Linebackers usually consist of Inside and Outside Linebackers. Defensive backs usually consist of Cornerbacks and Safeties.
Teams also use kickers and punters on special teams.
The object of football is to advance the ball downfield by passing and running.
There are multiple ways to score, touchdowns (6 points), Point After Conversions (1 point), 2-point conversions (2 points), Field Goals (3 points), and Safeties (2 points).
A touchdown occurs when the ball is advanced to the endzone. After this, a team can elect to kick a point after conversion, or run a play from 2 yards out to try to pick up 2 points.
A Field Goal occurs when a team kicks the ball through the uprights.
A Safety occurs when the defensive team tackles the ball carrier inside their own endzone.
The field is 100 yards long.
The current World Champs are the New England Patriots, though the Indianapolis Colts look the strongest thus far in the season.
Tom Brady is an American Football player, David Beckham is a soccer player.

A great sport, extremely physically demanding. Many of you foreigners keep talking about how it must not hurt because there are pads, you clearly have not played the sport. I'd like to see you guys playing linebacker with a hugeass fullback coming straight at you. Without helmets, american football would be just stupid to play, especially at the line. In America, we have a name for all of you types of people saying things like "Americans are pansys," maybe you've heard of it. "Racist."
Rugby and American Football, while similar are two different sports, stop acting like they are exactly the same.

A fictional sport from the "Friday Night Lights" universe. Originally a book by H.G. Bissinger, it was also adapted into a movie and TV series. The sport itself is mostly nonsense, but an american organization, the NFL, saw fit to to interpret it for use in the real world. It is believed that the acronym NFL was created by scrambling the letters of FNL. Unlike FNL, the NFL is unscripted. This has been received negatively by critics who came to love the characterizations and plot lines in FNL. Most people are patiently awaiting the day that the NFL is cancelled and FNL is renewed.
American Football was better in the book.

Probably the gayest sport ever. You're gay if you like watching "big, strong mean who probably aren't using steroids just to look cool" tackle each other on the ground while carrying a pig skin ball. Grow a pair and play Rugby you pussys

No footballs gay. were watching futbal or rugby

An extremely intense sport, popular in America, Canada, and played in parts of Australia, which involves large amounts of endurance, strength, and strategy. Brits like to bash it, only because the term "football" is one more thing Americans have that used to be only theirs (oh snap), and because soccer (futbol, football, whatever) is the worlds most popular sport, they can't comprehend the fact that people don't agree with the majority.

The sport has become an obsession in America, and is a giant part of American culture. The rest of the world is obsessed with the lovely little gentlemans sport of futbol, America is obsessed with the hard-hitting high impact sport of football. Were different, not ignorant. If you don't like it, fake an injury and hope America gets a red card
People get mad when Americans bash soccer, and insist that we don't understand and that were ignorant of other cultures outside our own. Though, ironically, everyone else does the same exact thing when it comes to American football... But the majority agrees with them, so it's ok

One of the dumbest and most dangerous sports created, most popular in America and Canada. Players generally weigh about 300-400 pounds and slam into each other for 3 hours. I am disappointed in my fellow Americans who actually like this garbage.

the most sped sport in the world, where you see fat man wearing 50 pound pads running around for 5 seconds at a time, and they still manage to break a sweat.
