A person, who is disagreeable or in low spirits may be presumed to go with his shoulders humped. Thence we have probably got the term humpy = despondent, hurt, put out[7], or of things: dull, miserable. To get (to have) the humps is probably a later formation and means about the same: to be despondent, to feel melancholy. It is rather common now-a-days in vulgar > coll. language.
