Spanish
Tener mala leche
/TEH-nehr MAH-lah LEH-cheh/
This Spanish idiom, literally 'to have bad milk,' describes a deeply ingrained, almost primal negativity or ill will that defines a person's character. It's not merely a fleeting bad mood or anger, but a fundamental disposition towards spite, resentment, or meanness that colors all their interactions and reactions. Such an individual habitually acts with a hostile intent, radiating an unchangeable unpleasantness that seems to stem from their very core, making them perpetually difficult and unkind.
Lit. To have bad milk
Used to describe someone who is habitually ill-intentioned, spiteful, or has a bad attitude, often without a clear immediate reason. It implies a general meanness of spirit or a predisposition to act with malice.
