<human>: Can you summarize the given text in a few sentences?

Actually the one who fucked up is one of my friends. Last summer he had a party at his place, and he lives a bit far, so when the party was over he offered to gave us a lift to the city. So here we were, 4 guys in a nice Mercedes.

He was driving in an empty street when he saw a convertible stopped at the red light ahead. Both drivers and passenger had long hair so he thought it was a couple of chicks. He stopped his car next to the convertible and opened the window (I was at the passenger seat, close to the other car), saying: "Hey! How is it going tonight lad...." and at this moment realized the driver was actually a guy, who looked at us half suprised, half pissed off and answered: "We are fine, thanks".
My friend could only say "ahhh... that's cool man" and quickly closed the window. The few seconds before the light turned green seemed to last forever...then my friend drove as fast as he could from the scene while the four of us were laughing crazy about his mistake. It ended up to be a great moment!

I'm not a native speaker so be kind if there are some errors in the text.
<bot>: My friend tried a pick-up line on a long hair guy while waiting at a traffic light because he confused him with a girl.
