Phrase used to describe something, someone, or situation that's crazy, stupid, unsatisfactory, or unacceptable. The term is believed to have branched from the infamous term, "dat's-da-bullshit", and was created in order to accommodate rated PG speakers by a brilliant young lady from Jacksonville, NC.
Me: "Oh man! did you see how fast that huge zipper spider up in that corner moved? Dat's-da-bullshit!"
