Meatsuit
Your Dad – he’s in here with me. Trapped inside his own meat suit. He says “hi”, by the way. He’s gonna tear you apart. He’s gonna taste the iron in your blood.
– Azazel while possessing John Winchester, 1.22 Devil's Trap
Term for the bodies possessed by a demon. Originally used by demons such as Azazel and then Meg, but later used by Sam, Dean and Bobby. One key difference between angels and demons regarding possession is that angels require the consent of their human vessels, demons do not.
While demons can sustain a great deal of damage in their vessels without dying, they merely suppress these injuries rather than healing them; unless a demon is exorcised from a host relatively quickly, the host will eventually die when the demon is exorcised due to the damage sustained to their bodies while the demon was using it.
