Got blood?

[lorenya]

I need help once more.

A little Indian guy and a white girl shoot hook shots in Harlem and some black guys watching them have the following dialogue that I couldn't catch the meaning of:

"That fuckin' man done gone and taught a white chick to shoot like us," one of the teenagers complained.
"That little guy got blood," another insisted hopefully.

Could you please explain me what they mean?
Thanks.

A little Indian guy and a white girl shoot hook shots in Harlem and some black guys watching them have the following dialogue that I couldn't catch the meaning of:

"That fuckin' man done gone and taught a white chick to shoot like us," one of the teenagers complained.

"done gone" is Black vernacular for an expression that is in itself a Southern colloquialism: to have gone and done sth

"Well, of all the things! It looks like Billy has gone and got married."
"I can't believe you've gone and lost the car keys."

This expression is an intensifier, stressing the verb ("to marry" or "to lose"). To "go and do something" is more remarkable than just "to do it."

This expression "to go and do something," especially in its past participle form "to have gone and done something," became "done gone."

So the sentence means "He has gone and taught a white chick to shoot like us" .... and THAT means "He has actually taught a white chick to shoot like us!"

"That little guy got blood," another insisted hopefully.

"got blood" means "to be Black, at least partly" -- to "have some Black blood in his ancestry."

The idea of the statement is that the speaker is hoping that at least the little guy is part African-American (thus accounting for his skill in basketball.)
