An idiom used to express feelings of regret and remorse, stemming from a realisation that one has willingly participated in behaviour that has led to an unforeseen and morally reprehensible outcome.

Having an unpleasant taste in youre mouth, mostly ment as a methaphore, but sometimes literally. It can be caused either by a feeling or an actual event.
Either way, if something gives you a bad taste in the mouth it is always bad.... really bad..
