CSB
The CSI version of "Cool story bro." If you get this...you probably just treated a forum like a blog, or you are generally disliked on your forum of choice (cough, NMB)
Seriously guy...do we have to know everything?
Guy: "OMG GUYS! I had a dream that I was choking on a chicken bone but it turns out the chicken was actually..."

Guy2: "Whoa whoa whoa Guy...I'll file that under CSB"

Guy: :C

CSB
Internet abbreviation, mainly used to indicate that the post to which it reacts is something you should say to people who care. Or it could be that the poster tried a little too hard to be cool in your opinion. CSB is short for "Cool Story, Bro!".
