It's a very good bloody question.

What the hell even is a Twix, anyway? It's definitely stocked next to all those chocolate bars that you know, love and trust like the humble Dairy Milk, the polarising Flake and the ever present Galaxy. But, then again, it's more than a bit biscuity. Ain't it? It's made of biscuit and is coated by chocolate, on this we can all agree. But what separates a Twix from, say, a chocolate digestive which is most definitely a biscuit. https://twitter.com/JOE_co_uk/status/683962844094840832 Where does one draw the damn line? That's what we want to know. And that's what Pointless host and chairman of the still controversial World Cup of Chocolate 2016, Richard Osman, wanted to know too. Osman is famous for a lot of things and one of them is his knack for thought-provoking tweets, like this bad boy. https://twitter.com/richardosman/status/832302754110521345 It was a concept steeped in gravitas.

@richardosman I know not with what weapons World War III will be fought, but I know this tweet may be the beginning of it.

Technical definitions proved frustratingly unhelpful.

@MxJackMonroe Also that would make a Penguin a chocolate bar. Unthinkable.

Some fun terms were conceived specifically for Twix's benefit.

Some big names got involved.

@Herring1967 I would have heckled vehemently.

You just had to feel for this poor soul, who found this to be the appropriate time to open up.

@richardosman someone bought me a Twix by mistake after I'd asked them to get me a Twirl a while back. Shocking.

Some genius ideas showed themselves. 

@richardosman In my house, it's a fancy tea straw.

Controversy was inevitable.

@richardosman Kit Kat is also a biscuit

You see, this is an interesting one. 2-finger feels like a biscuit, but 4-finger feels like a chocolate bar. https://t.co/wvH9amQhw5

Unfortunately, there was no definitive conclusion reached so we put it to you. What be Twix? Tough decision, eh?
