GEE-zer/ˈɡiːzər/

An old man, especially one seen as eccentric or cranky.

The cheerful old geezer sits proudly with his cap and walking stick.

Etymology

Geezer is traced to guiser, a masked or costumed performer. If that derivation is correct, the sense moved from someone in disguise to an “odd man,” then an “old man.”
