Is it true that Cas has a hot piece of ass?
This rumor is DEBUNKED.
Unfortunately, we do not have a reliable, well-documented source of measurement for the temperature of any piece of Castiel’s buttocks.
However, we assume that Castiel’s entire ass experiences thermodynamic equilibrium, and is therefore all the same temperature. We also assume that, as Cas has fallen (as was the case when we received this ask; however we will assume for all intents-and-purposes that an envesseled angel is also in thermal equilibrium with its housing flesh, as Dean and Sam have never commented on Castiel’s body temperature being odd), his ass is roughly the average temperature of the human body: 98.6° F/37.0° C.
The term “hot” is subjective, but Castiel’s ass is not particularly hotter than a normal human body. Therefore, we’re classifying this rumor as DEBUNKED.
