el niño period 

A natural phenomenon known as the El Niño Period occurs about 2-5 times a year and is a period that is significantly more painful than the person's usual periods. Symptoms such as cramps, irritability, stomach pains, mood swings, headaches, food cravings, bloating, and more are heightened in intensity and worse than they usually are. Like El Niño, these periods are an anomaly occurring at irregular intervals characterized by unpredictable acts and instilling fear in those nearby.

Mannnn, this is definitely an El Niño period! I'm so angry, I threatened to run over an old man with my shopping cart because he was blocking the cheez-its and I have NO RAGRETS.
