[BluffTHIS!]

That is a term almost exclusively used by evangelical protestants. It refers to Jesus' instruction that you must be born again of the water and spirit in order to be saved. More specifically it refers to what happens when you are baptized which they only do with older children and adults, unlike catholics and other protestant churches that baptize infants. It also has connotations of the doctrine of "once saved always saved", which means that after being born again no matter how degernate you might become later, you are still saved. Unless of course you weren't "truly saved" to begin with (another nice example of circular reasoning).
