Tailgation is shorthand for “Tailgate Nation.” Tailgations are communities of sports fans who congregate in the parking lots of American professional and college sports arenas. They erect tents and fire up barbecues, haul out portable beer pong tables and toss sad bags into little targets….all hours before a major sporting event. Deep South Tailgations, typically seen at SEC football games feature high-end RV’s, HD television screens and lots of fried chicken. Tailgations are defined by the activities and traditions held sacred by any tailgater: among them, BBQ, beer, games, and community. Tailgations grow organically, with traditions being passed down from one generation to the next.

As a faithful member of the Ravens tailgation, I’m proud to paint my face purple and join my friends every Sunday morning for crab cakes and Budweiser.

When a driver follows the car in front leaving little or no stopping distance especially at high speed.

This behaviour may stem from any or all of the following:

Lack of imagination.
Never seen pictures of a road accident.
Learning difficulties.
Road rage.
Someone who only managed to pass his/her driving test by giving the examiner a blow job.
Suicidal tendencies.
Having an extra chromosome.
Loneliness or pathological nosiness
Drink or drugs.
Being born with somekind of twat gene.
Driver is busy trying to figure out what the indicator lever is for.
A guy that is so dammed horny that he just can't wait to get to his mothers house.

Many female tailgaters like to put a sign in the rear window of their car stating that there is a 'Baby on Board'.

Tailgating may lead to a car fuck
Despite the 70mph limit I clocked 120mph while attempting to shake off the tailgater.

It was pitch black on that road, when I turned my car lights back on I observed that the tailgater had dropped back to reasonable distance.
