Define Whywolf Meaning

Whywolf
When someone drives a conversation into the ground by constantly asking 'why' and following up every answer with 'but why' over and over until there are no answers.

"I don't fucking KNOW why, ok? It just is! All the sudden you're a whywolf, asking me dumb fucking questions all up in here."

My fucking 3-year-old is in her whywolf stage. It's 'why this' and 'why that' and 'why, daddy, why'! It sucks.
