Bitch week: Refering to the week a woman is on her cycle/ monthly period...
mostly a term used by guys because when a girl is on her cycle they always say that the girl is acting like a total bitch and is a hormonal wreck when approached...
They most likely will be in a better mood if you give her chocolate to consume and do everything she says....
never mess with a girl on her bitch week.... you will regret it
Person A: "Hey dude whats wrong with your girlfriend this week? all she does is yell and demand stuff?"
Person B: "Dude! shes on her BITCH WEEK! i keep giving her chocolate to calm her down and its not working!!!!"
Person A: "DUDE! YOUR SKREWED!!!!"
