someone who pretends to be your friend, becomes close to you,
and leads you to believe you are the best of friends, until the truth eventually surfaces.

anyone who stabs you in the back are way insecure with themselves & they don't deserve to be in your life. forget them.
my best friend stabbed me in the back this year, more than once.

sam and her new horse-faced friend are backstabbers.
