Giant Global Graph (GGG) was notably used the first time by the inventor of the World Wide Web, Tim Berners-Lee, on his blog.

Tim Berners-Lee thinks about the social network itself that is inside and between social-network Web sites such as Facebook. He assumes that people can use the word "Graph" to distinguish these from the "Web". Then he says that, although he called this graph the Semantic Web, maybe it should have been called the "Giant Global Graph".
"GGG" has been used several times by Berners-Lee and by others in other blogs. GGG may be described as the content plus pointers of the WWW transitioning to content plus pointers plus relationships plus descriptions.

"Gay Ghetto Garbage" -- male homosexuals residing in extreme urban areas and inner cities (e.g., Bronx, NY) who refuse to seek education or employment, use and sometimes sell illicit narcotics but almost always marijuana, remain on public assistance; live off obese females (pretending to be heterosexual) or other (usually white) homosexuals in exchange for sexual favors. GGG usually resides with groups of GGG and are always in arrears on rent. They also live with an unwed mother and multiple half-siblings often in public housing.
