Apologies for the title, I found it difficult to describe.
If I say he took his hat and his leave I believe that is called syllepsis or zeugma. Another example would be he bolted his food, the door, and down the street.
But is there a term for an expression like where the gin is cold but the piano's hot?
Cold is used literally, hot metaphorically. It seems related to the first examples or does it have a more specific name - or no name at all?
