The week during which a woman has her period. There will be blood, an uncomfortable sense of tension and a bad tempered, unpredictable beast.

Take heed during shark week. If you show signs of weakness or aggression, you will be attacked. If you get attacked, it will be all your fault, infinitely more traumatic for her and you'll never be allowed to forget it.
Man 1-"Why is your wife glaring at you from the window?"
Man 2-"Shark week. She's looking for an excuse to strike"

Man 1-"Pub?"
Man 2-"Hell yes."

The time of the month when you do not want to be swimming with Sharks
'Sorry I can't go swimming, it's Shark Week'
'Sorry I can't have sex, it's Shark Week'
'No I'm not a bitch, it's Shark Week'

The week prior to menstruation in which a woman may experience extreme mood changes, cravings for chocolate, cramps and bloating.
Shark week is that one week of the month when my entire body rages against me and decides to attempt yet another mutiny. Ain't no mutiny like a shark week mutiny!

My breasts ache. My ovaries feel as if a tiny angry troll is squeezing them. I’m bloated like a dead fish and as if by some cruel joke, it’s the one week of the entire month that my husband finds me completely sexually irresistible.
Unfortunately for him, I am like a hybrid between a Praying Mantis and Black Widow spider. All I want to do is rip his head off and eat my young, not necessarily in that order.Pretty much, if you breathe you are in danger of incurring my bloody, hormonal rage and for some reason, I swear my teeth get bigger.

A week long television series about sharks. Their eating habits, how strong they are, how fast they can bite off your arm, leg, or rip you in half. They're fucking SHARKS. Watch it, and try to live every week like it's Shark Week.
"Did you just change the Channel?"
"Yeah, it was some boring documentary."
"Get the fuck out of my house. It's SHARK WEEK."
