I could take super small amout of cocaine, or the tiniest whiff of an 8ball...An "8 ball" is a quantity of cocaine. You kind of sound like my dad telling me about "goofballs" and "reefer" when I was a kid. Little experience but loads of hysteria about the unfamiliar.
D00d, I know what an 8ball is. The meaning was that I would just sniff in the general area of the 8ball of coke.
