A combination of slang terms gay and retarded. Although similar in spelling and sound to said slangs, gaytarded pertains to a ridiculous situation where and when no other single word can emphasize the degree of how gay and retarded the scene really is. Not related to homosexuality or mental illness.
Note: Gaytarded should only be used in the most extreme level of social depravity.
Doug: Come see my band man, we're totally cool!
Andy: Yeah? What's it sound like?
Doug: Well we sound like Tool, but instead of drums I've elected to beatbox!
Andy: Doug- you and everything in your world is fucking gaytarded.
Doug: Yeah we're called "Aesthetic."
Andy: I will end you, gaytard.
When a person can't decide if they are just gay (not as in homosexual as in they do something stupid) or retarded...so then the person is both making them gaytarded
An insult used to make fun of people who are gay whilst at the same time, calling them a retard. The subject of the word doesn't have to actually be gay as it just uses the word "gay" being an insult, not what it actually means.
