"Not Going to the Circus" tantrum
A temper tantrum/meltdown of epic proportions. Usually caused by one not getting his or her way. This comes from the children's television show Caillou.
My grandmother threw a "Not Going to the Circus" tantrum because she was worried there was not enough money to gifts for everyone for Christmas. Also, my five year old great cousin had one because she couldn't buy the latest Barbie doll at Walmart.
