it's when you open your mouth, and nothing but dishwater comes swirling out.

everything washed in but nothing came out quite clean enough. water spots and smudgings of unknown substances.

you'll call bluff but the dish washer, he's not to blame. he's just doing his job. the water, it likes to wander, it has a mind of its own. and right now, its mind isn't on doing the dirty work.
