Top definition
An image (sometimes literally, in drawing/artwork form) of a person's online alter ego. Not who you are in real life, but what you project onto the net. Often much more attractive, mysterious, alluring, and sociable than your real life self. Frequently illustrated in various states of undress and possibly carrying a weapon.

A portmanteau of "internet" and "persona."
In the real world, I'm just some socially awkward dork... but online, my netsona is xXxLordThrillKillxXx, a weightlifting quiet loner with a troubled past who might or might not have killed someone, you never know. Here's a picture of him.
