Basically, you make a wish and the next person has to grant you the wish, but ruin it. Then they have to make a wish, and someone else does the same etc.
For example: I wish I had a dog Then someone else would post and say:
You get your dog, but it gets hit by a car before you can hold it.
You smile, but then realise that your school taught you the wrong description of smiling, and it turns out you've been frowning your whole life. People around you wonder why you're 'smiling' at them, and you lose all social acceptance.
Everybody stops SAYING they're depressed, but they start SHOWING they're depressed by knifing somebody elses wrists instead of their own. Bex is arrested for causing all the chaos, and ends up knifing her own wrists in gaol with a toothpick.
I wish I had 10 more branches of the British Army, and they were FULL 24/7.
Lol, You get your pepsi, but whilst drinking it, a tooth comes out, you swallow your tooth, and slit your throat, You are taken the hospital ASAP, but it's too late.
