lifer
A classification for the most perfect woman you've ever seen. The term comes from the belief that if you land such a woman and she decides to end your relationship for any reason, you must subsequently end your own life. The reason being that you would never be so lucky to land another such woman so anyone else would be a downgrade.

It should be noted that this is an exaggerated term and you should never kill yourself if a girl breaks up with you. Idiot.
Matt: Did you see that girl at the Racetrac?

Carlos: The one with the glasses?

Matt: That's her.

Carlos: Oh, yeah. Total lifer.

Matt: God help us.
