I came across the phrase 'to come over one's hoot' several times while watching a British TV series and I can't get the meaning of it from any definition of 'hoot'.
The context was like this:
A and B are talking on the line in their workplace and when B doesn't follow A's instruction, A gets agitated and says this line: "B, I'm going to come over your hoot and broadcast this(=B's serious mistake)."
As they're talking on the phone and work in the same building, I presume this might mean that A is going to come over to B's desk but I'm not very sure.
I also wonder how any meaning related to this scene could come from the word 'hoot', for all I could find out about its definition as a noun were a. a shout, outcry b. honking sound c. laugh or a cause of laughter d. a cry of an owl.
So could you help me find out the meaning of the phrase (or idiom) to come over one's hoot and explain how come it has such meaning?
