"Grean," a slang term widely used in Thailand, refers to a person who acts like a bastard or to the act of bastardization in the internet and cyber-world. "Greans" don't have the awareness of a usual person, and do many things without thinking.

"Greans" can be referred to as a noob or newbie, but are worse than them. "Greans" can cause chaos in many games, online-societies and forums. They act like they know everything, in spite of the fact that they often don't know anything.

The term "Grean" was initially created as a slang word by someone in the forum of the Pramool site, the most nation-wide website of Thailand, and was always used in the Ragnarok society, The most renowned online game in Eastern Asia. Started by a group of children who had the crew-cut hair style, and they were always insulting anyone who passed in their sight, mostly young children. When this slang word was used so many times, people consequently referred to people who behaved in this manner as "Greans." "Greans" are now present in many forums and sites.

However, the group of "Greans" suddenly get angry when they are called "Greans," because of the term's connotation. "Greans" also consider themselves as the center of correctness, which is rather removed from reality, so they created the other slang word "God" to refer to themselves as a professional or pr0. This word can also be seen in many forums and sites, like "Grean."
