Alabama Jack o Lantern 

A festive Halloween sexual act that requires the working of fingers around the rim of the partners anus in order to widen the hole, also cleaning out any filth that might be discovered in the process (much like carving open the top of a pumpkin and cleaning it out). Once the anus has been loosened and cleaned, a lit flashlight is dropped into the anus, providing a captivating glow like a beautiful Jack-o-Lantern.

I thought the interior light was on in Pat’s minivan at the fall festival parking lot, but to my surprise, it was the soft glow from the Alabama Jack o Lantern he gave to Jeremy in the back seat!
