Other forms: dropouts
A dropout is someone who doesn't finish a project or program, especially school. If you quit high school before you graduate, some people will call you a dropout.
Whenever you quit something, or don't follow through on a commitment, you risk being called a dropout, which is a fairly derogatory term for someone who withdraws, quits, or drops out. If you withdraw from college after one semester, you might jokingly describe yourself as a college dropout. The word dates from about 1930.
