something that a person finds so interesting that they cannot let go of it
What is the origin of the idiom "rabbit hole" and when to use it?
The idiom "rabbit hole" originates from Lewis Carroll's famous novel "Alice's Adventures in Wonderland." In the story, Alice follows a white rabbit down a rabbit hole, which leads her into a whimsical and unpredictable world. The term "rabbit hole" has since been used metaphorically to describe a situation where someone becomes deeply interested or obsessed with something, unable to let go or move on easily.
