Idiom
Over the Hill: Origin and Meaning
Meaning
Being no longer young and unable to do what you once did. A humorous way of saying that someone is old, no longer attractive and energetic, or someone who can’t keep up with the young ones anymore.
Origin
This idiomatic expression, therefore means that you are old, past your prime and past your best.
Now, with the 30s being the new 20s and the 40s being the new 30s, the top of the hill mark has somewhat shifted and has lost its value. That said, people still use this expression in a fun-loving or ironic way, when they want to tease someone who has reached an important milestone in life.
Examples
– Oh my, you’re turning 41! You’re definitely over the hill now.
