How can I grow a coconut palm so that its trunk is angled (or “dancing” as we say in Belize)?
These palms are the product of some major force, like wind or water, that has partially knocked over the plant. Most of the root structure remains connected, so the plant can continue to grow, although it's tilted, or even lying on ground. So if you want to force a plant to do this, you become the "major force." You can start with a plant that has some growth to it, and by shoveling the soil away from the roots on one side and under the roots on the other side, you can maybe push it over somewhat. Or you can plant a palm so that it is tipped at the angle you want. Or you can start with a young palm, and force it to grow tilted by staking, weighting, and tieing.
