Lawn Pornament
Any seasonal lawn decoration that has been or can be used as a sex doll or sex toy. Can be inflatable or rigid and may or may not be modified to support deviant acts.
My grandma called the police when she saw a drunk college student from down the street defiling her prized inflatable Santa Claus. When the Police arrived, they found him passed out holding a Christmas elf. He had apparently sealed the deal with Donner, Prancer, Rudolph's mouth, and Frosty the Snow Man. When questioned, he claimed that he became addicted to Lawn Pornaments after dropping acid while watching a Family Guy marathon.
