What's that banner in your sig reference to?
Ooh! This is a good one! I assume you are aware with the term ninja'd? Yes. Yes you are. A ninja train is when that happens, only with about six posts instead of one, and all of those posters are responding to something that was six posts or more ago for them. It tends to happens about once per thread in the RB thread, often around page forty, (and continue for a few pages into the new one) when we all subconsciously start speeding up for some reason. The term was coined there, and ninja trains are AWESOME.
