So, someone posts something they have or something they're happy about, and then the person below ruins it, and posts something they're happy about. Ex:
Me: I just got a promotion!
Pick: I'm the CEO, and I fired you.
I found 20 dollars on the street!
Pang: I bumped into you, knocking it out of your hand, and took it.
I inherited millions of dollars from my uncle dying!
and so on...
Subject: Haha! Not anymore!
