You know how you see your breath when its cold well when you fart does a puff of smoke come out your but

well when you see that smoke, its when the hot reacts with the cold, so im guessing that yes, when you fart there will be smoke o something.

Sure does and if you light your buddies fart you can feel the heat.

Steam yes, smoke no.

Unless someone is blowing smoke up your ass.
