<human>: Can you give me the gist of the text in a nutshell?

Ahhh, summer of '08. Me and my friends partied all the time. So when me and my two other friends decided to borrow our other friend's car and take it for a joy ride, we didn't think twice about it. 

So here we were going about 60 on a small country highway. It was about 1 am so there were barely any cars out. The driver thought it was a good idea to swerve the car back and forth between both lanes. The car we were driving was a '95 cutlass, I believe, and it was in the shittiest condition. We were all high so we weren't really that worried. We were jamming out to Lil Wayne's "Fireman" when all of a sudden my friend that was driving yells, "OH SHIT!" 

I really remember being jerked from my seat (I was in the backseat) and laid out. Then, all of a sudden, I am hovering in the air, inside the car for about a second then immediately slam down on the ceiling of the car, which was now upside down. The only injuries I had were cuts on my elbows from broken glass and a bump on my head. My two other friends had their seat belt on, and also walked away.

The weird thing about this was during the accident, my mind went blank. No thoughts on whether this was the end of the line or my life flashing before my eyes, just complete blankness.
<bot>: My friend flipped the car we were driving in, didn't have a seat belt on and walked away nearly unscathed.
