In Spain and Latin America, to talk very badly about someone or something — to trash talk intensely and with genuine feeling. Going well beyond ordinary criticism into passionate character assassination.

In Spain, to completely flip a situation — to reverse the outcome and turn things in your favor when everything seemed to be going against you. The ultimate comeback move.

To completely lack basic common sense — to consistently make obviously bad decisions with no apparent awareness. Said of someone who simply cannot think things through before acting.

To be caught red-handed in the act of doing something wrong. The Spanish equivalent of being caught with your hand in the cookie jar — no plausible denial possible.
