Top Definition
A person over 20 (sometimes, way over 40) who refuses to go into adulthood, thus wearing clothes, having attitudes and maintaining tastes from their teen years, or adopting today's teens tendencies. A little more mature than a kidult, but not much.
Being and adult is boring. I'd rather go on as a teendult.
