There is one thing that is absolutely certain about throwing a dead cat on the dining room table – and I don’t mean that people will be outraged, alarmed, disgusted. That is true, but irrelevant. The key point, says my Australian friend, is that everyone will shout, ‘Jeez, mate, there’s a dead cat on the table!’ In other words, they will be talking about the dead cat – the thing you want them to talk about – and they will not be talking about the issue that has been causing you so much grief.[1]
In the UK we call it a dead cat strategy.

Sounds like a super long way of describing a “distraction”.
