They are Hidden Machines. You can get them from mostly gym leaders, but sometimes, a person along the road will give you one. Professer Oak gives you one after you defeat all 8 Kanto leaders. You can use them in and outside of battle. You can't make a Pokemon forget a hidden machine move yourself. If you want to make a Pokemon forget a hidden machine move, go to the move deleter in Blackthorn city in Johto.
