Definition & Meaning of "peak times"in English

What does "peak times" mean in British slang?

The structure combines "peak" (unfortunate or bad, as in the previous term) with "times" (periods or situations), forming a noun phrase for difficult moments. It is used in British Multicultural London English (MLE) and UK slang to mean difficult, rough, or bad periods in someone's life or in a situation. People typically say "I'm going through peak times" or "It's peak times for him right now." The term originated in early 2000s London street and grime culture, extending the meaning of "peak" to describe extended difficult periods, and remains common in UK youth slang.
