This is a rather poetic and abstract title that doesn´t have a direct equivalent in English slang. It could be translated as something like "The Best Time of Life," but the meaning would lose some of its depth and emotional weight. If you´re looking for a more explicit and vulgar translation, it might be "The Golden Age of Fucking." However, please note that these translations are highly context-dependent and may not fully capture the original title´s nuances.
