The term 'Cumdog' has started trending on Twitter, the reason why is hilarious

The term 'Cumdog' has began trending on Twitter and fans can't quite work out why.

For some of us, though, we know the exact reason – and it's pure gold.

And yes, we did say 'Cumdog'.

In the wake of Australia's 4-1 defeat at the hands of France in the World Cup, social media absolutely blew up when a hilarious but rather rude word started doing the rounds.

To your average Twitter user, the term 'Cumdog' would have no relevance whatsoever.

But for us Aussie football tragics, we know exactly why it went viral.

Enter, Jason Cummings.

The Scottish-born Australian international is a cult hero Down Under.

A loveable larrikin, he goes by the nickname of 'Cumdog'.

And well, now that Cumdog has gone international by making his World Cup debut, it seems global supporters of the beautiful game have fallen in love with his nickname too.

So when the big man came on a substitute in the 56th minute, social media sleuths wasted no time in churning out hilarious memes to pay homage to him.

Unfortunately for Cumdog, we struggled to make an impact on the game and barely had a sniff at goal.

That said, you can guarantee fans - Australian or not - will be calling for him to start in the Socceroos' clash against Tunisia.

As for the rest of the team, they eventually became overwhelmed by the French, despite bagging the opening goal of the game and dominating possession for the first 15 minutes.

With the likes of Kylian Mbappe and Oliver Giroud breathing down their necks, the players began turning over possession cheaply which subsequently lead to goals – four of them, to be exact.

Giroud went on to write his name into the French history books, equally Thierry Henry's all-time scorer's record with 51 goals.
