haha you have hit upon one of my pet peeves! In the nursery world, this is supercropping:

You are probably referring to what us potheads have claimed the term to mean, which is the practice of forcing a single plant to produce a LOT of growing tips.
Let the plant get to 5 nodes.
Pinch off the growing tip. If you want to get fancy, pinch it so that you remove the folded-up LEAVES on the tip but leave at least a chunk of the NODE MATERIAL, whcih may then grow several new shoots.
Either way, this 'releases' lower nodes to grow branches.
Let each new branch get to 4-5 nodes, and repeat until you have as many fresh shoot sites as you like, but be warned, you will have to increase air flow and keep the very center of the plant pruned pretty clean or you end up with dead air (and dead tissue) in there.
