Biologically programmed- (women)
A blanket term meant to absolve women of all responsibility for being sex obsessed, hormonal, needly, clingy, crazy, irrational, borderline retarded sacks of estrogen filled shit. Basically, it states that since women only ovulate for approximately twenty years and produce two eggs a month in that time period, they are on a sacred mission to find the perfect sperm to fulfill their quest to produce hellish little offspring. This thereby gives them license to act like a total bitch towards other women (since every guy could potentially be "the one") and to be suspicious and skeptical towards men until they prove beyond a shadow of a female doubt (like a doubt, but with a pea brain) that he finds them "special" and "likes them for who they are" and "likes me and only me". This justifies their incessant calling, their tyrannical demands for time and attention and their self centered insistence that the man "have the means to provide for the offspring", since they have to be "certain" of their decision since their egg is so fucking precious it makes a Faberge egg look like a decoder ring at the bottom of a box of Cheerios.
It's not her fault man, she's biologically programmed as a woman to get attached if you fuck her good a couple times.
