The funnest word in the English language to use out of context when used in a response to a serious question. It misleads and confuses the interrogator. The real definition means " tending to associate with others of one's kind" but no one in their right mind knows that. When a person is responding to a question it is always best to follow up the statement with "That's why they call me gregarious." Coined from Brad Pitt's line in the movie The Assassination of Jesse James by the Coward Robert Ford. .
Girl: So what are we exactly?
Boy: Well I've never been one for serious relationships really. Guess that's why the call me gregarious.
Another way of saying somebody is people needy, and has a herd like group mentality.
Most people are not really gregarious, most people like a balance of space and company. People who claim they are gregarious all the time are full of shit, and usually have lots of people around them at all times as a crutch, since on their own they're weak people.
Someone who so loves other people that she strictly avoids them, to protect everyone.
Looking down from her solitary balcony at the empty street, she thought warmly of her many friends, and those she hoped someday to meet, glad that they were nowhere near her, happy for the moment to be the gregarious loner.
