Ok, so the point of this game is just what the title says. Overreact! The first person posts a sentence, the next poster overreacts about the first poster's sentence and then post a different sentence. Like this.
P1: I love chicken.
P2: OH MAI GOSH, chickens will rip your head off and feed it to rabid rabbits!!! WHY!? Why not love turkeys???
~I eat cheesecake.
The third poster will freak out about the second poster's sentence and so on.
I guess I'll start.
~The purple dog just jumped on my bed.
