look up any word, like fleek:
 
1.
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."

2.
A line from the 1995 film "Friday" starring Ice Cube and Chris Tucker that is becoming increasingly popular for no reason. Just like twerking, it has been around and well established for many years, but has recently become more mainstream as white girls attempt to use it, most often incorrectly and oblivious to its origin.
White girl #1: "Bye Felicia!"

White girl #2: What does that mean?
White girl #1: Look it up on Urban Dictionary.
Black girl: *facepalm*

When a person does or says something that pisses you off, instead of letting their irrelevant ass get to you, their name becomes "Felicia". You can then say the words "Bye Felicia" as a way of dismissing them from your life, and showing them they hold no relevance to you.
Person: You're a little bitch.
You: I dont have time for your bullshit you know, Bye Felicia!
Person: Who is Felicia
You: Who are you?
