A blanket used primarily during masturbation to cleanse yourself of the billions of little soldiers whom were born and raised without fear and set on a mission. This blanket interrupts this mission and is usually thrown out after 4 or 5 uses depending on the CC of each load.
Frank: Hey, where did my blanket go?

Matt: Andrew took it in the bathroom and is using it as a Spanket Blanket. He'll be out in 5.
