Not sure if there's already a game like this, but i'm starting this up anyway XD

The game is called Chain Reaction. You post a two-word post, and the next poster has to use the second word as their first word.
I sincerely suck at explaining stuff so here's an example:

Poster 1: Base Ball
Poster 2: Ball Hog
Poster 3: Hog Warts

I'll start us off!
