A Western Australian man has sparked a domino effect of mismatched thongs after drunkenly pinching someone else’s following a gig in the coastal town of Dunsborough.

Jason had been at a Fat Freddy’s Drop gig on Sunday, and awoke the following day to find he had come home with an odd pair of right-footed thongs.

He took to a Dunsborough community Facebook page to apologise for his mistake.

A woman named Amy then responded with a picture off the left-footed half of the thong combo.

However, she also admitted to further complicating the thong swap by taking another woman’s pair of thongs after she couldn’t find her own.

Jason quickly realised his actions had led to a “domino effect” as people tried to locate some form of footwear in the absence of their own.

“Looks like a domino effect as well. Much apologies to you and the next person in line. Innocent victims,” he wrote.
