A cum-bubble fart is a wet gaseous emission smelling of cum from a guy's asshole that he lets out after he's been fucked by several dudes in his bunghole.

Usually the outcome of some dude on dude action. It is the product of man cum and air pressure build up in the anus thus producing a bubbly cum fart.
