Party years consist of the five year span between 20 and 25 in which women generally experience their peak SMV. During the party years women begin to prefer dating men older than themselves.
Rollo notes, "A woman’s late party years are often the stage during which she entertains the hope that she can ‘civilize’ the Alpha Bad Boys who satisfy the visceral side of her hypergamy into assuming the providership role the other side of her hypergamy demands and is increasingly becoming more urgent for her – most Alpha Widows are made during this period. However, it’s during the Epiphany phase women (conveniently) make the rationalizations necessary for justifying this ‘fixing’ effort." He also notes:
Bear in mind, no woman actually “skips” the Party Years. She may participate to greater or lesser degree in the opportunities those years open up to her, but she’s still keenly aware of those opportunities and realizes the window for them closes as her beauty and fertility fade. She sees her girlfriends, maybe sisters, indulge those opportunities, or she may live them vicariously through media that panders to them, but regardless, she’s feeling the pull of knowing she could potentially realize them.
