biscuit rule

The modern family rule where a divorced, single, or unremarried parent isn't allowed to date anyone that isn't at least 15 minutes older than their first natural born child.
It's called the "Biscuit Rule" because 15 minutes is also the average time it takes to properly bake a biscuit. The rule exists to prevent the single/divorced parent from embarrassing their kids by ever making them say they're older than a prospective step-parent.

My daughter's college roommate asked me to a movie, but, because she's younger than my daughter, I had to comply with the 'biscuit rule'.

Guy 2: "I feel bad for you, now you can't get sexually close to her."

hand rule

The standard against which optimal breast size is gauged in seeking a suitable mate, etc.

The optimal breast size is equal to the amount that can be fit in one's hand; any less is not enough and any more is excessive, wasteful, and unnecessary.

The curve follows a sharp Gaussian/Cauchy–Lorentz function and distribution.

f (x; 0,1) = 1 / π (1 + π^2)

This is also known as the Breast-Volarity curve.

Person 1: Wow, she has exquisite breasts.

Person 2: Eh, they're too large.

Person 1: Nonsense!

Person 2: Don't forget the Hand Rule.
Person 1: Ahhh, good call.
