Isn't the name "git" (and therefore "github") itself considered pejorative? IIRC, Linus did name the tool after the British slang word.
"Git is a mild pejorative with origins in British English for a silly, incompetent, stupid, annoying, senile, elderly or childish person. It is usually an insult, more severe than twit or idiot but less severe than wanker, arsehole or (redacted)."
