It comes from the fact that a male chicken, a rooster, rules over the females, or hens. The place where birds sit is called a roost, so if you "rule the roost," you dominate the rest of your group. They do what you tell them, and defer to your decisions. Sometimes you see this used humorously to mean that in a marriage, the wife "rules the roost" instead of the husband.

Roost is a noun (a roost) and a verb (to roost).

A roost is a place where birds perch -- the dominant bird rules this area and bosses the other birds around. A rooster is a male chicken. This is a humorous way of saying that the man may rule the house, but his partner (often a woman) rules over him.

The Roost was created in 2005.

The duration of The Roost is 1.33 hours.
