I watched a TV talk show headlined “The tank hits hot topics”，and what does the word “tank” mean?

Question

I've just watched a TV talk show with a headline of “The tank hits hot topics”,and I guess it might be a shorter form of "think tank"? If it was, is such a shorter form of "think tank" acceptable and common in English? I have a suspicion that in this headline, the word "tank" is purposely used to convey a double meaning.

I am not sure if that usage is a pun.

Answer 1

There's no pun here¹, just typical headline-ese: "the Tank" here is shorthand for "some of the stars of the show Shark Tank", "hit" is headline-speak for "talk about", and "hot topics" means more or less what it sounds like.

_{¹ Whether or not it's a pun to name a show that's not about wildlife Shark Tank is a different question.}
