a petite, non asian girl. A girl so small, you just wanna grab her and put her in you're pocket. Pocket girls are usually pretty spunky, and are real easy on the eyes, if you catch my drift. One does not have to date a pocket girl to have one. All one has to do is simply proclaim that said pocket girl belongs to them, and if someone hasn't claimed her, then she is you'rs. There is a limit to how many pocket girls you can get, that limit being 3. it is ill advised to have more than three pocket girls , as this results in overdose. A group or herd of pocket girls is referred to as a giggle or a twitter.
