Internet Cassonova 

Someone who is lacking in confidence in real life so he hits on women on the internet. Most likely a fat guy living in his mothers basement, or some 14 year old.

OMG I'm such an Internet Cassonova, I totally just cybered with the hawtest chick! Now I need to go find some cheesy poofs so I can fall asleep in the bag crying myself to sleep, again.

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.
