What it means
A codger is an old man, usually a bit crusty, set in his ways and quick to grumble about how things were better back when. Old codger is the standard phrasing, said with a mix of affection and exasperation. He hates the new bins, the new money and the music, but he will still lend you his ladder.
Usage examples

Where it comes from
Codger has been knocking about in English since the 1700s as a word for an elderly man, often one seen as odd, tight-fisted, or a bit grumbly. The exact root isn't nailed down, but it's long been especially tied to British usage, and old codger later softened it into a more fond, teasing phrase.
