In Latin America, someone with a toxic personality who intentionally causes harm with their words or actions, like a slow-acting poison.

In Mexico, someone who acts with malicious intent while keeping a low profile — doing harm or causing trouble in a sneaky, subtle way that doesn't look obvious at first glance.

In Mexico, an expression of mild skepticism or a soft challenge — doubting whether someone will actually do what they claim, and waiting to see if they prove you wrong.

To function without energy or real awareness — running on autopilot due to extreme exhaustion. Moving through the day like the undead, technically present but mentally completely absent.
