haircut rave
a concert where people have more layers in their hair than in their personality and the music is just background noise.
I went to a haircut rave and got distracted by my friend’s hair. I forgot the song was even playing.
The guy next to me was so busy flipping his hair that he knocked over the soda machine.
At the rave, the beat dropped, but no one moved. They were all too busy doing their hair.
