1. When a female does something extreme that may or may not be a result of what her ovaries are doing, yet they get blamed for it.
2. Overreacting in a female, esp. as a result of being on her period.
Eric: "Dude, Sarah really broke up with you just because you ate the last of the brownies?“
John: "yeah, but she'll be back within about a week or so. It's her time of the month, so she's just ovary-acting."
An Ovaryaction is when a female responds over the top in any given
context based on emotional charge rather than logic. It usually occurs
within the menstrual cycle because her Ovaries get angry and cause
the Ovaryaction thats how the word was formed.
