To break or wreck something, destroy what was working. Can also mean to take someone out or put an end to a situation — permanently.

In Spain, to hook up or have a sexual or romantic encounter. The social objective of many Spanish nights out — the reason half the people are there in the first place.

To go out on the town, to party hard. The Spanish juerga is serious — it starts late, runs long, involves food, drink, music, and the refusal to call it a night. Going de juerga is a full commitment to having a good time.

To be in a foul mood, with a bad attitude and difficult character. The 'mala uva' (bad grape) is Spain's metaphor for concentrated bad temper — concentrated and sour.
