ずくめ

ずくめ is used after a noun to describe a situation, condition, or set of things that are entirely or almost entirely that noun. It emphasizes that the thing in question dominates or characterizes the whole, leaving little or nothing else. It can carry a neutral, positive, or negative nuance depending on the noun, but it often has a somewhat emphatic, colloquial feel. Commonly used for negative or tedious patterns (mistakes, troubles) but can describe abundant positive things as well. It is less about frequency and more about a complete or overwhelming presence of the described noun.
