When Brits are talking, I notice this construction more from them than any other anglophone people, where they will end a sentence with an uncommon adjective and noun as a punchline, usually with some sort of paradoxical tension between the two words. It goes like this,

“Oh the film was wonderful, it was a kind of farcical whimsy.”

“I’ve never quite understood politics. It all strikes me as a kind of formless melee.”

“It was a risky move, a kind of calculated dare.”

Edit: Some of you lot are misunderstanding me. I’m not asking why people use different words. I’m asking about this particular construction. I think it’s ironic that so many of you are telling me to “increase my vocabulary m8” and yet you seem to not know what the word “construction” means. It’s a sort of combative projection.
