What does STAB stand for?
A. STAB stands for Same Type Attack Bonus. Let’s take Slowbro for example. Its two elemental types are Psychic and Water. If you were to use Thunderbolt, which is an electric move, it will do normal damage to it. However, if you were to use surf, then the attack power is would be 95 * 1.5 = 142.5. If you decide to use a move that is the same elemental type as your Pokémon is, the damage is multiplied by 1.5x. So using Psychic with Slowbro would also result in 90 * 1.5 = 135 attack power.
