"What are the most forgotten moves?"

Today while going through Emerald, I discovered a move called SMELLINGSALT which Hariyama learns at lvl 33. I went over to Bulbapedia to find out that it was renamed Smelling Salts in XY. It does extra damage to paralysed Pokemon but heals them. It has 10PP and 60 base power. I didn't know about this move until my Hariyama got to lvl 33. What moves are the most forgotten moves that you know about?And also, can someone explain to me why the move is named SMELLINGSALT and its relation to its description? via /r/pokemon http://ift.tt/2uTwLab
