I just had some fun with Google. Apparently I am the only person ever to have used the phrase “metonymical cigarettes” (There are two — in the whole internet — other pages that contain “metonymical cigarette” singular).
If I smoked, Metonymicals would definitely be my brand. We could have the Metonymical Man, who would be sort of like the Marlboro Man, except more allusive.
“Metonymicals . . . because smoking should mean something.”
