You're A Twat Greeting Card
You might think the world of your mate, but it doesn't mean they're not a complete tool and friends being friends you wouldn't want them to change from their twattish ways anyway. You just need to remind them of this every once in a while. A greeting card with a funny picture of a man in a 1990s shell suit walking against a blue background. White bold text in front of him reads You're a twat.
