a plastic mac
1 used when speaking to a man whose name you do not know:
Hey, Mac, watch where you're going!
In my own town certain commodities can be bought, but not a plastic "mac" in a downpour!
It is not the sort of thing you could tuck under your mac and take into a bank or anywhere else.
But this will lead to the same old thing—the detective in the grubby mac hiding under the bed or in the car boot to get evidence.
These days, service men and women are more likely to go to work in civvies and, if they wear uniforms, they will be under a mac.
At times riding mac fashion has been empowering worn in order to convey an authoritative tone, commanding attention and respect in some of lifes more difficult or threatening situations.
