scrub stock

Someone who is second rate and unimportant. Similar meaning to the phrase Ham & Egger. It was originally used to describe inferior farm animals. It's often used to describe second string or lower players on a sports team. It's also used to describe employees who are not valuable. More recently, in its short form, scrub, it's used by African-American women to refer to African-American males who are unemployed, without a car and/or without any money, but who still delude themselves into thinking that they are worthy of attention from attractive women.
