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.

To rest on your laurels — getting too comfortable after past successes and stopping the effort. Whoever 'falls asleep on their laurels' loses what they earned through overconfidence.

To pester someone relentlessly, nag without stopping. The 'tabarra' is that repeated, grinding annoyance that ends up irritating everyone around it.

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.
