If you're a parent to a child of a certain age, you'll be well aware what 'Fortnite' is.

The rest of us are basically aware that it's some kind of video game that has inspired various dances (like 'flossing') and that kids go absolutely bonkers for it. Apart from that, we're a bit clueless.

And we're not alone, either, as Lady Gaga proved yesterday.

She took to Twitter to ask what exactly 'Fortnite' (or 'Fortnight', as she put it) was, and the response she got was probably what you might expect of Twitter. Straight answer? Forget it.

Moral of the story - don't ask questions on Twitter.
