variations include fkia "Fucking Know It All"
use the rfkia when the person is a known celebrity
use fkia when talking about teenagers or in-laws etc
A lot of sports casters and talk show hosts are rfkia's, People like Bob Costas, Howard Cowsell, Bryant Gumball, Keith Olberman, Rush Limbaugh, Sean Hannity, Laura Ingraham etc.
Not all talk show hosts are fkias, Don Imus and Bill O'Reilly are just stupid assholes.
could be worse, at least he's not Dr Phi,l he is a rfkia.
