Meaning
To misunderstand what another person has said or intended, often because messages, instructions or assumptions have become confused. Usually refers to a mutual mix-up rather than deliberate deception.
Origin
The image comes from electrical and telephone wiring: when connections are crossed, signals can reach the wrong destination. The figurative expression grew naturally from the spread of wired communication; it does not refer to literal crossed thoughts.
Examples
I think we got our wires crossed — I meant Thursday, not Tuesday.
Sorry, we got our wires crossed about who was booking the tickets.
We must have got our wires crossed; I thought the meeting was online.
