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
