How it's used
This term describes someone who is not just mean, but calculated and underhanded in their malice. It implies a hidden, snake-like quality where the person smiles to your face while plotting your downfall. Unlike simply being mean or angry, it carries a sense of deep-seated, strategic cruelty.
Examples
He is such a sinister person, always playing dirty tricks behind people's backs.

Common mistake
Learners often confuse this with 惡 which just means fierce or mean. Using 陰毒 to describe a loud, aggressive person is incorrect because it specifically highlights the hidden and treacherous nature of the behavior.
