Y'all ridiculous.
Unless he made up the name hisself, it was probly what his folks called him.
Dudes names could be Boo-Boo, Snoopy, Snoop, Lil C, Lil Bigs, etc. I know hella niggas with the same name that way. So if dude say he bizzy he bizzy. Y'all on some MTV shit. You never knew two mofuckas with the same street name?
