Noun: Whack-er

1. A wanna-be hacker...A person who claims to have "god-like" or "Hacker" computer skills without actually possessing the abilities.

2. Someone who uses hacker toolkits with no real hacking knowledge.
George is a whacker. He tried to "hack" work when he got fired, but he got busted by the cops because he did it all from his home computer without hiding his IP address.

Whackers are easily spotted because they often misquote technical facts from television shows like CSI and NCIC and make unfounded claims about their ability to use NMAP.

The Internet has spawned an entire group of whackers... users with little computer education and open access to hacker-grade toolkits. Imagine this group of whackers as a group of children playing with guns... it's only a matter of time before someone gets shot.
