Plym

A Plym is a university aged girl that possesses a huge personality, most likely including many feisty traits. Plym's tend to be small, dark haired and are more often than not wearing a heel (better used to fight with). however Plym's do have nice streaks that are normally apparent if the Plym in question likes you. Overall being on good terms with a Plym is a valuable asset.

In dialect -

Boy 2 - yeah, i hear she's a right Plym.
