Code word for: A woman's period. aka "that time of the month"
It's the time of the month when crazy shit starts happening, like at the circus.
My girl was acting like a total bitch. The circus must be in town!

I could not get layed because the circus is in town!

Why are you bitching so much? Is the circus in town?

Can also fight back with immitating circus music when the bitching starts
