A Riley is a person who can't make up their own style and has no personality. They talk about other people behind their back and are at heart mean. Having a bad reputation for asking out almost every guy in the grade, she is an annoying person who can't be original. Another word for a BIG nerd.

Get the Riley mug.Someone with little to no understanding of basic human anatomy, let alone the functionality of most things for that matter. Will often ask you to engage with bizarre hypothetical situations.

Anon: That's why your pupils expand, Riley.
