A rather popular nonsensical expression people spat out for various reasons and mainly used as a verb. Also, one of my favorites to how bullshit got its meaning. But, it is of uncertain origin.
Back in the 16th century, bull had another meaning to Victorian people: it meant to fool, mock or cheat. This kind of bull came from a Middle English derive, bul, meaning falsehood.
