As the name implies . . . giving your specimen as much prey as it will accept, while keeping conditions on the warmer side of recommendations for the species. In tarantulas, this has been used to get males to reach maturity faster and be larger when they get there to better ready them for breeding projects.
With scorpions, I'm not sure if excessive feeding gets them there faster or not, but hobbyists will sometimes use a "hot box," a small heated and insulated container to raise temps in an effort to grow the specimen faster.
These have the slight disadvantages of shortening the overall lifespan, but with male tarantulas, the primary reasoning is to prepare them for breeding faster.
If your emperor scorpion stops eating, don't panic.
Be nice -- you were a noob once, too
