To no longer be in a place that one knows or where one is comfortable; to be in a completely unfamiliar and/or discomfiting environment. A reference to The Wizard of Oz, in which Dorothy, upon arriving to Oz, says, "Toto, I've a feeling we're not in Kansas anymore." It can actually be quite shocking to finish college and enter the workforce, because suddenly you realize that you aren't in Kansas anymore and life operates in a totally different way now. As we walked into the bustling streets of Delhi, we knew we weren't in Kansas anymore.

Said when one sees someone for the first time in a long time. Wow, it's so great to see you! Don't see you much around here anymore since you moved.

No longer having or afforded the innocence, naïveté, physical advantages, or lack of responsibilities associated with youth. You shouldn't try to tackle such demanding hikes—you're not a kid anymore. I could tell he was trying to con me like he used to do, but I wasn't a kid anymore, so I told him where to shove it. You aren't a kid anymore, Tom. It's time you started acting like an adult.

No longer; not as of this point or from this point onward. I've spent my life waiting for opportunities to come to me, but not anymore! From now on, I shape my own destiny! A: "Do you still work for GloboCorp?" B: "No, not anymore. I'm with UniCo now."
