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. The idiomatic use of eating serves to convey both the initial positive, tasteful, experience, as well as the negative, distasteful, after-effects.

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..

The feeling you get after working as a fluffer!

A term usually labeled upon musicians by obnoxious teenagers.

(Some teenager) Dude, have you heard the latest fallout boy song?

(Musician) No, those guys suck. They have no variety in their music and their excuse for a guitarist just plays a few simple power chords throughout their songs. I doubt he could play a single sweep arpeggio if his life depended on it.

(Some Teenager) Dude, you have terrible taste in music.

(Musician) What makes you say that?

(Some teenager) their singer sounds cool, and they have bitchin lyrics.

(Musician)Lyrics are the easiest part of making music, and singers are the most overrated and most replaceable part of any band. The skill and quality lies with the people playing the insturments, and the people writing and arranging the music riffs as a whole, fallout boy fails at both.

(Some teenager) Hi jim! I see you have the latest soulja boy cd! (I stopped listening to that guy after 3 words.)

(Jim) Naw, this is the latest from miley cyrus.

(Musician) Wow, and he says I'm the one with bad music taste.
