a person who is fake and betrays you in some way that they lied to you. Like if you told your friend a secret and they promised to never tell anyone,then next thing you know they told the whole school,then that person is fake for promising you something they cant keep,and a liar for lieing to you,so why not use fakefalsefier instead of fake and liar.
Your friend is a fakefalsefier cause she lied to you.

p.s.-fier is said like fire
