An term used (unofficially, of course) by corporate human resources departments for the number of outside responsibilities/interests an employee has. The lower the number, the more desirable of an employee you are.

Married? That's a point. Have kids? Another point. A sick parent? Another point. And so on. Anything that might distract you from work is a point. The more points, the higher your drag coefficient, and the less desirable you are to employers.

Yet another reason why there are so few 40-year olds in IT.
