I resent your describing it as "a favourite tactic", it is a response to what I believe to be habitual lying - I really do thoink you owe a justification of this accusation.

If you use a phrase often enough it is fair to describe it as a favourite. How many people you use it on is an irrelevance. There are a lot of things that I resent too, Jim, including you addressing me as 'boy' and avoiding answering a simple question by repeated requests for me to answer yours, which I have every time. You seem to be conveniently ignoring that too.
