#CoryBernardiWankPuffin is trending on Twitter in Australia.
The viral hashtag is the result of some widespread opposition to South Australia senator Cory Bernardi, who recently had to defend himself against allegations of homophobia from the Opposition leader. It also appears to be related to the Safe Schools Coalition, which Bernardi is opposed to.
As for the Wank Puffin part, there's no clear reasoning for it. It might be a popular insult down under, for all we know. But it also might be related to a viral tweet at the end of last year, in which a man claimed his elderly mother's WiFi password had been automatically generated as "wankpuffin7". It also could be related to the usage of the term to insult Donald Trump.
This appears to be the first usage of the hashtag:
Despite no one really knowing what the wonderful phrase means, it's becoming a meme on the social media site.
So there you go. That's why you might see a slightly strange hashtag floating around on Twitter.
