"Half, plus seven" is the age-old dating rule for dudes. It justifies the dating of younger women, within reason. The formula begins with each dude's age (for example, 22). That age is halved (22/2 =11), and 7 is tacked on to the divided result. Therefore, a 22 year old male may legitimately date an 18 year old female, a 25 male may date a female of 19.5, and a 30 male may date a female of 22. While there is no technical ceiling on this social anthropological formula, there is a point at which common sense takes over, and it just becomes disgusting. For instance, this formula should not be used to justify a 60 year old man dating a 37 year old female.
Half plus seven examples:

Guy's age: 20. Formula: (20/2)+7 = Minimum acceptable age of female: 17.

Guy's age: 25. Formula: (25/2)+7 = Minimum acceptable age of female: 19.5

Original definition: A man is most attracted PHYSICALLY to a woman half his age plus seven. (Rule of thumb).

Modern twist invented by frustrated younger guys: Minimum age that a woman must be for an older man to romance her.
He's infatuated with her , and she lacks any interest in him, so he cites this debunked "half plus seven rule" to justify his frustration with the guy that she's dating.
