He meant to say “bugaboo” but said a word that ends with the same two syllables. The damning part is that he was talking to a black woman when he said it. I’m going to say it was a Freudian slip. Or maybe not. I don’t care. I just hope he catches a lot of grief for it.
Freudian slip or not, it is very unlikely that a word one has not used aloud previously would slip out at the wrong time.
