Parties that usually center around a group of people who tailgate to a football game (originated in the South). Once there a party, typically, with food (barbeque or grilled) and alcohol, is held in the parking lot.

Recently tailgating parties have begun to take place at other sports games, symphony performances, and nascar races all over the U.S.
"What started out with a few sandwiches and a couple of beers before the game...has evolved the tailgate party into great American sports tradition...
A group of friends can drive to any outdoor setting, park their cars and pull down the tailgates - get out the grills and prepare a feast!" --Chiff.com

Get the tailgate party mug.
A normal tailgating party thing but better and with less safety features. There are no seatbelts or anything else that would prohibit you from falling off allowed
Ted Bundy once went to a mobile tailgating party with some basic bitches he killed and got so drunk he tried to stand up but accidentally stepped on his dates vagina causing her to profusely bleed and need 24 stitches.
