Grishna aka cakeboy, is a gaming slang term used for a person who is clinically obese. This person often plays for a online gaming clan/community, and often uses the words "noob", "boon" and/or "owned/pwned".
They often try to take pictures of themselves with a "emo/myspace" feel, and often refer to themselves in "body type" as "a little big built".
Mostly northerns fit this description, and they are usually aged between 15 - 19 years old. They do not have a girlfriend, and are still often a virgin. They masturbate heavily, often while gaming and often work within fast food restuarants.
