lightning slut
A typical adult woman of the 'slutty' variety, however her sexual encounters are over in such a short time that they have been called "lightning fast". Not to be confused with lightning bug, because their rear ends rarely glow. This is a unique strategy for the experienced slut, as it allows her to have many more suitors in a short amount of time, therefore leveling up her experience as quickly as possible. However, it is not always intentional. Some lightning sluts have enough sex to be called a slut, but they are just bad at sex.
