Abrasive - Wikipedia

A substance used for grinding or rubbing down surface e.g, emery, carborundum(sic).



An abrasive personality is a one that hurts, annoys, irritates and criticizes anyone and anything, without any seeming remorse. They are of two types: one who lacks self awareness and does not know they are abrasive, and the other who knows full well that they are abrasive and take pride in it.
