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

To do absolutely nothing — to sit around scratching yourself while everyone else hustles. In Argentina, rascarse (literally scratching yourself) is the image of ultimate idleness: hands doing nothing useful, contributing zero.

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.
