[DONALD TRUMP] was, by both his friends’ description and his own, a rambunctious kid who got in trouble a lot and who was a bit of a ruffian. From the youngest age, about age 6 or 7, he pelted the neighbor’s toddler with rocks from across the yard. He pulled the pigtails of a classmate. He got into a physical altercation with one of his teachers, and so he was someone who was kind of a rambunctious kid, even obnoxious by some accounts, and he says that he hasn’t changed since second grade. So that kind of in-your-face provocateur character that we’ve come to see in the campaign is something that traces back very cleanly and consistently to this childhood as kind of a tough kid.

I believe the word you are looking for is “bully”
