When a bitter or metallic-like taste appears to have taken over your taste buds for days, causing all foods and beverages to be distasteful and unbearable. A possible side effect of eating rancid pine nuts.
Even my Tim Tam cookies taste bad because of this pine mouth. I knew I shouldn't have eaten those candied toasted pine nuts that came with my salad, but I couldn't resist them at the time.
