Hot shit

Why is hot shit better than cold shit? I can't think of any situation where the temperature of the shit would have a significant impact on my response to it. I suppose if I was buried up to my neck in shit, my preferences for the shit's temperature might vary depending on the weather, but it would be of minimal concern compared to how I might extricate myself from said shit itself. I suppose it's one of those phrases that has evolved without people giving it much thought, but now I have, I will be more careful about my useage in future.
