A woman from Hunan in China, who got dumped by her boyfriend for being overweight, appears to have got some quite exacting revenge on her ex.

User Xiaoxiao on Weibo, the Chinese version of Twitter, has blown up the social platform with a public message to her ex which claims she is sending his mother a bar of soap made from her liposuctioned fat as a Spring Festival present:

Yang Xiaolei, do you remember last year's Spring Festival? Since I can't go home with you this year, I've made a piece of soap from my own fat to give to your mum for washing up. Chinese New Year - the time to surprise those low men who can only judge a book by its cover!

She posted what are supposedly before, during and after photos of the procedure:

It may shock you to learn that Xiaolei did not take the stunt well.

Xiaoxiao posted a screenshot of an argument the pair apparently had via text message:

Xiaolei:

Why are you making me look bad on the internet?! It was already over between us, you didn't need to go to the hospital to suck out fat and disgust me! Damn, do I judge people solely by their appearances? You didn’t need to disgust my mum, or what? F--k you b---h!

Xiaoxiao:

You said I was fat. I'm sending your entire family some soap, believe it or not!

Xiaoxiao's story, which shows if nothing else an impressive commitment to poetic justice, has not been verified, but it's attracted thousands of shares and comments since it was posted last week, many of which are negative.
