I think I posted somewhere already why I chose BIGSHaW, but anyway no hurt in telling it again
I used to be BIGSHOW since a guy I worked with used to call me like that, then one day, after 1 year break from CS, I returned to this community and there was this guy named TheBigShow....so I just modified my name a little bit by making SHOW into SHAW with small a, final result BIGSHaW
