Its not anything, it's everything, it doesn't mean anything but it can be used in any sentence at any time for any desired effect with the right tone of voice.
It is simply a noise to make whilest to tone of your voice gives an inclination of what you are talking about.

An expression of sympathy. Not necessarily sad nor happy, it can describe self-pity or be a reply of empathy. It is ideally used when "yes" or "no" is not appropriate but yet the situation still requires some conclusion.
Self-pity: "Bleh" - I'm bored, tired and agitated but I'n not ready to shut-up and go home yet.

Reply: "Bleh" - I hear you and I feel for you, man!

In the uncomfortable quiet of a dying conversation, instead of farting, the word "bleh" just completes the situation.
