And the fifth best president ever:
“Smart” is one of those terms that has several different meanings.
In the common idiom, “smart” is sometimes wrongly used as s synonym for “intelligent” or “learned”.
More often, “smart” refers to a very keen eye for dress and mannerisms, presenting a polished and highly developed sense of appropriateness for the occasion, especially in a formal setting, and is immediately noted by all the connoisseurs in the room.
“Smart” may also refer to the sharpness of pain from an injury that abrades or opens a cut on the skin, but not necessarily a deep injury, only one that triggers a lot of undesirable sensations and possibly an outcry.
And sometimes “smart” is reserved for the wise-guy response, the arrogant braggery that goes with an overly inflated ego, the worked up quick retort, that sometimes leads to a fat lip or black eye.
Pick the one that applies to this particular situation.
