I am two words. I can only be lost, never won. Think of me and you'll lose. If you tell someone about me, they'll always play me. What am I?

I am known for measuring length, but I do not have lines or numbers. You might slip on me.

I start out tiny, but soon, I'm a dad, My teeth appear out of the palm of your hand. Careful or you'll find me stuck in your head, Many a young parent might wish me dead.

What Everyone wants to become, but no one wants to be.

A fallen, famous king from a kingdom closed in walls, I met a tragic end, a small child caused my fall. My loss mourned far and wide, beyond my kingdom there were tears, I inspired countless memes, in terms of fame I have few peers.
