Acronyms are a strange thing. They express information in easy to use brevity, but without resorting to long and complicated words. But here’s the thing: they only work if you know what they mean.
Some people use them to gain superiority in a conversation or an argument in order to bamboozle everyone and seem superior. But actually, to everyone else, it just sounds like a load of steaming sewage spewing from their face and makes them an arse.
However, there is one rather childish way of getting your own back with someone like this, and that is to reply to their nonsense by nodding sagely and saying “YAAA” after they’ve finished each statement. This has the effect of letting them think that you are agreeing with their incoherent babble and also that you understand it. But in actual fact, you’re responding with your very own acronymical insult:
YAAA = You Are An Arse. You’ll find that German people are particularly good at this.
