middle-aged man; old guy
Casual and often derogatory term for a middle-aged or older man, similar to 'geezer' or 'old dude'. Used familiarly or dismissively depending on context.
That old guy is reading magazines at the convenience store again.
I got annoyed when they called me an old man.
Familiar, sometimes slightly irreverent term for a Buddhist priest. Less common than the general 'middle-aged man' sense.
I got a lecture from the priest at the neighborhood temple.
