What is “the hottest seat/seed in town”? I am not sure if it’s a
seator something else. I heard it a few times on “CNN” when a new upcoming “Larry King Live” program was being advertised. Also what does it mean “in town” here? It seems that it has nothing to do with a physical human settlement on some territory, but rather with some sphere or even some time period, I am not sure.
It’s a play on words.
The “hottest seat in town” can refer to a popular/hard-to-get ticket to an event such as a play or game (similar to “it’s a hot ticket”).
“Being in the hot seat” means
a high-pressure situation in which a great deal of attention and scrutiny is focused on a person or organization
— per Wikipedia
So, the “hottest seat in town” is a popular place to be, but also a place where you’re under scrutiny and being asked questions you must answer.
