According to FUNKTIONARY:

scarecrow – a lifeless well-hung mindless man crucified in a garden who sacrifices his humanity for his manhood. 2) a man with a good looking head on his shoulders—but with no cultural consciousness. 3) a man who hangs aimlessly in the middle of a garden—guarding a coveted fertile piece of land. 4) a man hanging from a pole and a pole hanging from a man—working the fields at hand. 5) a man who has seen everything but learned nothing because his body was there but he was never present. 6) anyone who looks at life through the eyes of others believing their truth, logic or belief system. 7) a man who is hung-up on himself and thus acts as if a pole was stuck up his butt for a spine. 8) anyone who needs help to “get down” or “get off” without falling apart. 9) a threatening ruse to distract one’s enemy when there is no real or actual danger. A man whose life is spent suspended in air lives a groundless existence. Women are all-too-often stuck with a man on a pole or stuck by a man with a pole, either way, it’s still no more than being in a pole position—but who’s in the driver’s seat? Living life with a scarecrow can be scary—while he’s falling apart will you go to pieces? Should he become dis-membered will you re-member him? Garden hoe; the backbone of the scarecrow. Scarecrow—like Bob’s Big Boy—should he stay or should he go! (See: Woodman, Strawman, Osiris, Garden, Egotesticle & Straw Boss)
