Know it like the back of my hand 🧠🖐️
Meaning
To be extremely familiar with a place or subject.
Origin
Imagine a time before detailed maps or GPS. If you wanted to navigate a town, you relied on your knowledge of its streets. Now, picture your own hand. It's something you see and feel every single day, in every position. Every crease, every knuckle, every fingertip is intimately familiar. The phrase emerged because, for centuries, the back of one's own hand served as a familiar, readily available, and constantly visible reference point. If you knew something as thoroughly as you knew the landscape of your own palm, you truly knew it inside and out.
