The hot yard decoration for Halloween this year is two inflatable skeletons getting it on.
One is sitting on the ground with his knees bent, and the other is STRADDLING him. A company called Goosh is selling them on Amazon for around 80 bucks.
People are not super happy about these being available due to the suggestive nature of the decoration. You can see the Goosh product photo below or can buy one for yourself here.
