shart cloud
To release enough hot fart gas in one movement from your anus hole that that it smells like you have shit your pants, and in being hot the fart rises straight up to head height for maximum effect.
I was grocery shopping today and let out a fart in the deli isle that brought a tear to my eye. I had to move leaving a shart cloud behind as to not draw attention to myself. It smelt like I had shit myself.
