Okay, time to talk about farts, something every woman loves to do. Seriously, we do. We find it just as funny as anyone else does.
But as for a snakes fart... It sounds like a puff, fluff, floof, silent but deadly... that type of thing. Sometimes when their poops and urine is watery sometimes it will sound like you pressing your lips together and blowing out air, only quieter. And I have never witnessed a snake cough so I could not give you any info on that one.
