The Late Philip J. Fry

The phrase ponerse al día means to get up to date or to catch up with someone. Non-compositional in its social use: it signals reconnecting after time apart, not just updating information.

A standard distress call in Latin American Spanish, used in genuine emergencies. More urgent and less casual than '¡ayuda!', and less melodramatic than '¡socorro!' in everyday contexts, though both are understood everywhere.

A cheer of celebration or relief. In the episode it is used with pointed irony immediately after a setback, which is a common comedic device. The word itself is not sarcastic by default.
