The word referring to the non-aroused state of the penis, before or after sexual activity.
This is basically where the penis is in its more natural state, when it isn't stimulated by the rush of blood, that creates an erection.
It occurs prior to sex, and generally afterwards, unless one is taking the little blue pills.
This is where the blood is flowing normally, and not being rushed to the penis, by some form of attraction or mental command.
Noteworthy: Generally used as an adjective to describe a soft or flabby state, not necessarily just for a penis.
