A person who claims to be or is on the righteous path of life. No longer cool enough to hang with old friends. Makes bullshit excuses when asked to hang out but really cant go out cuz they're bound by a significant other.
Person 1: yo you hung out with john recently?
Person 2: nah man he turned into a straight church niggah.
