Internet Casanova
A guy who frequents the internet just for sex hook -up's and has no interest in a relationship of any kind except sex. To them the internet becomes a tool to a giant black book or a bordello to get some action from as many as they can.
Eg:These women are dumbshits they think I want a relationship because my profile says so but i really want to be is an internet casanova and just have fun. After im done with my booty call ill check my emails for new girls.
