I read a news starts with the saying "It's getting very hot in the hot tub for Senate Republicans at the moment." I understand that it says the topic is very hot, but why say "very hot in the hot tub". why use "in the hot tub"? There are lots of thing. Why it should be "hot tub"? why not use "hot water/ soup /pot"? Is there any story about "hot tub"?
The writer is likely referring to the 1983 Saturday Night Live sketch "James Brown's Celebrity Hot Tub Party," starring Eddie Murphy, which uses "too hot in the hot tub". It's often played on "best-of" compilations and would be familiar to any SNL watcher or anyone familiar with 1980s American pop culture. The content of the sketch isn't relevant to the article; the reference is only to the catchphrase.
