Someone who is completely oblivious to the fact that traffic is completely stopped on the other end of a large intersection and continues to drive out into said intersection simply because they have a green light.
When the light turns red and the crossing traffic gets a green light, there is now nowhere to go because this moron is blocking traffic, creating a gridlocked situation in extreme cases.
I was 25 minutes late for work today because some gridlock douche turned Route 9 into a parking lot near the mall.
I stopped at the green light because I could clearly see traffic was bumper-to-bumper on the other side. So when the jackass behind me started beeping I yelled back, "Sorry, I'm not a gridlock douche like you."
The act of going to, and experiencing all that comes with a Gridlock 64 show. This includes, but is not limited to, the music, singing, dancing, and drinking. In a nutshell, it is to succumb to the effects of good music, good friends, and good times.
Gridlock delirium is what happens to a person's psyche when they are stuck in traffic for 3 hours or more without movement; often causes the person to text or call people they have not talked to in many years(includes ex's), and often this leads to feelings of regret. After the anger and random texts(calls) have ceased, the person will probably begin to become hungry and/or horny and wish to fulfill their desire with the person behind or in front of them in traffic; once again leading to more regret.
A friend was stuck in traffic so long he started experiencing Gridlock Delirium; he became so bored he started reading his car manual, calling ex's he hadnt talked to in 3 years and eventually scheduling a lunch date with one. The driver in front of him started to seem oddly cute until saw him pour a yellow substance from a coke bottle out of his window.
