(the girl says her Mom is detoxing in California; the boy says:)
“Cool! Party at your house?”
“Can’t. The feng shui man’s there. Our karma’s, like, really blocked, you know?”
Roto Buddha. Only in the Heights.

*
the Heights are the Brooklyn Heights in New York
the dialogue is between two seniors from a private school

I couldn't google up "Roto"
and I don't quite get the meaning of "Roto Buddha" in general
because feng shui isn't a Buddhist thing
(then again, "Buddha" here might stand for anything new-age-generic, no?)

any ideas?

thanks!
