You might find the OM5 to be a good option if you still want a “real” camera that’s not point and shoot and still really small. With a pancake lense and big pockets it should be pocketable. I got a used EM5 which is the old version of a very similar body and with the pancake lense it feels like a point and shoot with good ergonomics and lots of manual control options.
I think Lumix has some options as well.
It’s really just a shortening of “a week from Saturday”, so more of a dialect than language thing.
