Larrikin is an Australian English term meaning "a mischievous young person, an uncultivated, rowdy but good-hearted person", or "a person who acts with apparent disregard for social or political conventions".[1]
In the 19th and early 20th centuries, the term generally meant "a lout, a hoodlum"[2] or "a young urban rough, a hooligan",[1] meanings which became obsolete.[2]
