When someone talks about
something that no relevance to the current topic of conversation, or when someone talks about a topic that no
one cares about or makes no sense. This originates from a conversation with a young child who instead of answering the
legit question from an adult started talking about unicorns.
Person 1: It’s really
cold outside today, maybe we should go shopping tomorrow.
Person 2: I wonder if I could
fly if I could run faster.
Person 1: That’s unicorn talk.
