Explanation
だらけ is used to describe something that is filled with or covered by a large amount of something, usually something undesirable or negative. It emphasizes abundance or excess rather than a simple state. It often carries a slightly negative nuance, like “scattered with” or “littered with,” and is common in everyday spoken Japanese as well as writing.
部屋中がごみだらけだ。
へやじゅうがごみだらけだ。

The room is covered with trash.

彼のノートは間違いだらけだ。

His notebook is full of mistakes.
