ass is grass

Shorthand for the full expression of, "Your ass is grass, and I'm the lawnmower!" Implies that the person making the statement has directed certain doom of one sort or another on the person to whom the statement is directed. When the shorthand is used, it simply means that the person is doomed, has made an unrecoverable critical error or has otherwise made a mistake that puts ones own life, freedom or choices at some degree of peril, which is not necessarily always or even most times fatal. When the full statement is used from one person to another, it also means that the person making the statement believes with a high degree of confidence that s/he has total control or domination over the person to whom the statement was directed. Examples of this in society and popular culture include authority figures such as parents, military officers, etc. The notion that "ass is grass" has anything to do with post-death bodily decay and/or fertilizer is a misdirected urban legend by pompous buffoons trying to impress someone with a creative but ultimately false etymology.
