Apparently "sideshow" is thug talk for thugs doing doughnuts in the street in their cars while their thug buddies watch the "sideshow" and attack traffic trying to use the streets.
I always thought a sideshow was a circus or carnival act and that doughnuts were sweet pastries.
Thank you to you for providing an accurate definition, and to those who provided other explanations which made me laugh!

To those who complain about children being in a car with their parents after midnight: sheesh! Have you never traveled with children—maybe the celebration was at a grandmother’s house?
Have you never gone nearby with your children and let them fall asleep while you and the other parents kept talking and then driven home?
There are a million legitimate reasons for children to be in a car with their parents at all hours of the night. It’s not like they are running the streets alone without their parents!
