Big Fuckin' Dog - when you're tired of classifying you gigantizoid mutt in casual conversion, you can answer with this acronym to reverse the awkwardness of a pretentious ass waiting to lecture you on his/her canine's bloodline. Your mutt/rescue had better be 100+ lbs. 150lbs+ is ideal.

prick: "oooh, what kinda dog is 'he'? "

prick: "oooh, right. they are soooo good with kids."
