To push hard, put in serious effort, or work intensely. Also means to speed up or apply pressure to get results. Popular in Spain whenever something needs full commitment.

To keep your feet on the ground — be realistic, practical and grounded, not swept away by fantasies or illusions. The mark of a mature, sensible person.

To blackmail someone — manipulating them by threatening to reveal damaging information unless they comply. Chantajear goes beyond ordinary pressure; it's calculated leverage, the dark art of weaponizing someone's secrets against them.

To break into uncontrollable laughter, laughing to the point of tears. The reflexive version of humor without restraint.
