1. Always be one step ahead of your opponent.
2. Know your opponent well enough to poke fun but not to make them cry.
3. Try to incorporate a name, such a nickname or light insult, to add emphasis.
4. Surprise them and keep them on their toes at all times.
5. Remember to keep anything in mind about the person that can be used against them. Do not poke fun at a traumatic experience, I mean embarrassing stuff.
6. Practice, practice, practice preferably with a trusted friend or future opponent.
