My mouth tastes like a chicken yard
Has anyone else heard "my mouth tastes like a chicken yard" to describe the nasty taste you get with a cold?
No. But I was raised on a chicken farm and can testify that this an apt phrase. That would be one dry and foul (fowl) mouth.
I once said to a Doctor that I had a bad taste in my mouth and she said yes, that happens, a taste like the bottom of a bird cage.
