5SOS have changed their Twitter names and profile and the most bizarre hashtag is now trending.

Fans have been tweeting #DogeFamily after the stars put up a photograph of a dog as their main images and changed their names, leaving us all asking: "WHAT IS GOING ON?!?"

Well, we did some digging and found that 'Doge' is a internet meme based upon pictures of a Shiba Inus, and a slang word for dog.

The meme often uses grammatically bad phrases on images to represent feelings with the words nearly always randomly spread across the image and use Comic Sans font. Right, that's cleared that up then.

But despite all of the fun and games, 5SOS star Ashton Irwin was left unimpressed after he was accused of blocking fans from meeting him and his fellow band mates last night after a gig.

A post on Twitter read: "Earlier before 5sos left Brisbane, Ashton did request for fans to not be allowed in the hotel."

Ashton swiftly replied: "@WeUpdate5SOSFam super hugely mega false."

But there was more annoyance when the fan account tweeted: "Ashton is sick today and hungover from their party last night, I'd be quiet and reserved too.. Give him a break smh."

The 5 Seconds of Summer hunk then added: "@WeUpdate5SOSFam I had two drinks." They've been told! Oh dear..
