Three words that should be banned from the English language, as in:

“I shoulda made the move on him when I had the chance. He woulda seen what a great guy I am and we coulda connected.”

“I shoulda made the move on him when I had the chance.  I woulda seen what a jerk he really was and I coulda moved on instead of standing there all night like a lovesick puppy.”
