I initially thought of "eight ball", which does feature in one of their more dramatic stories. But apparently the term has other or mixed provenance. And things like the urban dictionary provide multiple definitions.
Just what is a "baller?" From origins perhaps in basketball to urban street culture to drug culture... to modern day "hard ass", type A or whatever? Just what do people mean when they call themselves or someone else a "baller"?
It seems to be one of those terms that depends significantly on the specific context within / to which it is applied. Yet people will just say "baller" -- like my acquaintance -- and leave you to fill in the background. In other words, you have to be in the know, to know what they are really saying.
Which, IIRC, per some of the definitions I encountered, is actually part of its definition. :-/
An eight ball is 3.5 grams of coke, AKA an 1/8 of an ounce.
