A tailgate party is a social event held on and around the open tailgate of a vehicle. Tailgating, which originated in the United States, often involves consuming alcoholic drinks and frilling food. Tailgate parties usually occur in the parking lots at stadiums, before and occasionally after games and concerts. People attending such a party are said to be tailgating. Many people participate even if their vehicles do not have tailgates.

The idea for eating out of the back of a car may have started in 1866 with Charles Goodnight, a Texas farmer. He noticed that the cowboys he employed needed a way to eat on the road, so he transformed a U. S. Army wagon(马车) into a mobile kitchen. There, hungry workers could eat, relax, and socialize after a long day of working.

Nowadays, people tailgate for lots of reasons, everything from college football games to Jimmy Buffet concerts. In schools and communities, some athletic departments, coaches and parents of student athletes rely on post-game tailgating parties to build community and support for their program and team.

What people consider essentials(必备)for tailgating spreads isn’t the same across the country. Different areas of the country have their own favorite foods for tailgating. While foods like burgers and chips may be common everywhere, some areas have specialties. For instance, those in Louisiana may consider jambalaya a tailgating must, while those in the Midwest simply can’t go without brats. And the West Coast? Don’t be surprised to see grilled fish or pasta. While dishes may differ from area to area, one thing is the same across the country: beer.
