Larry: Jeebus! look at this word! It's not even a word, it's a 3 word phrase - what a stretch.
Moe: That dictumhead probably thinks getting published here makes him Ernest Friggin' Hemingway.
Curly: Or Marian Webster.
Moe: Get around here, you!

DICThead 

1. One who spends their time creating entries in online dictionaries with the intent to defame others.
2. Likeminded people who reinforce this behavior by adding repetitive and intellectually challeged definitions.
3. Moonbats who create bogus definitions purely for propaganda's sake.

The pathetic DICTheads are having a field day with Dick Cheney.
