CSB or cool story bro originally cropped up in the south west of England.
The original cool story bro comment followed either a genuine cool story or as a satirical way of telling your friend to fuck off.
After a Conservative MP used the saying at a debate, it was deemed 'uncool' by the youth. Thus the abbreviation 'CSB' was born
Friend 1: "I fucked her so fucking hard her fucking fanny came off"
Friend 2 "CSB"
