The term "ragger" is a slang word primarily used to describe a person who is notorious for teasing, playing pranks, or harassing someone relentlessly. Synonyms for "ragger" can include troublemaker, bully, tormentor, jester, joker, teaser, mocker, heckler, or agitator. A bully is someone who intimidates others through fear or aggressive behavior. A jester is someone who enjoys making others laugh, but sometimes this humor is at the expense of others. A mocker is someone who ridicules someone else, while a heckler is someone who interrupts and jeers at a speaker or performer. No matter the synonym, being a "ragger" is never a positive quality.
