A friend of mine who is a psychologist was explaining to me what a Freudian slip is. He gave me the clinical definition, but I still didn't understand.
He said, "Like the other day, I was at the airport, and the airline clerk was a beautiful blonde and showed a bunch of cleavage. I went up to the desk and said, 'I need two pickets to Titsburg---I mean, two tickets to Pittsburg!"
He said he was of course very embarrassed, and that's a Freudian slip.
I said, "Oh, yeah. It's like the other morning, my wife and I were eating breakfast, and I meant to ask her for some more coffee. But I said, "You fucking bitch! You ruined my life!!!' That was just a Freudian slip."
