Bully noun
1 a person who teases, threatens, or hurts smaller or weaker persons
As I googled the meaning of the word, I recalled reading in the news how some celebrities share their stories of being bullied sometime in their childhood and in that way reaching out to the smaller people ("us") and make the world a better place.
It's great that they open up to the public and show us that they were once regular individuals, capable of being hurt and belittled (or until now since they are almost always the topics of tabloids, blind items and targets of paparazzis).
