Achieving NoFuC is the way to force the narcissist to leave you alone.
If you are being pestered by someone trying to seduce you who you have no interest in.
If you are being badly treated by someone who is bullying you.
If you are being repeatedly harassed by someone you were once in a relationship with.
If you are being smothered by someone who seems pleasant but is behaving over the top at the outset of your involvement with them.
If he or she just will not leave you alone.
You are in all likelihood being hoovered by a narcissist, whether it is in seduction or whether it is devaluing behaviour. Whether it is at the outset of the relationship, during the relationship or after the relationship such behaviour where this person will not leave you alone exhibits the behaviour of the narcissist.
To deal with them, you need to achieve NoFuC.
