Ah, I see. We don’t tend to put it to the mouth. It’s more “fuck you”. Apparently comes from demonstrating to the French that you still have your bow-drawing fingers and intend to use them. British archers captured by the french would have their first two fingers removed to prevent them launching arrows.

In the UK two fingers up is a rude gesture and it comes from battles with the french. If they caught a British archer they removed those fingers so they couldn’t fire a bow. So sticking them up at the enemy and gesturing was showing they had them and would use them to fire arrows at them. I am not an historian, though, and this could just be one of those tales that sounds so true everyone believes it and passes it on.

We do? Can you describe the gesture? Maybe it’s so ingrained I don’t even recognise it. Or I need to learn it. Then I can use it at everyone today.
