When someone says that they're leaving and you could really give two shits less that they are. Their name then becomes "felicia", a random bitch that nobody is sad to see go. They're real name becomes irrelevant because nobody cares what it really is. Instead, they now are "felicia".
> "hey guys i'm gonna go"
> "bye felicia"
> "who is felicia?"
> "exactly bitch. buh bye."
