A genuine GFE would be like this ... you sit on the couch together watching TV and she is watching "The Voice" wearing her tracky dacks, ugg boots, and sloppy joe, and eating a whole packet of Tim Tams.
And then you put your hand on her thigh and say "you look really pretty tonight Shazza, I like what you've done with your hair"
And she says "fuck off ya cunt, I'm tryin' to watch TV"
That's pure GFE
