caught with (one's) pants down

Taken by surprise. Caught in a vulnerable (often embarrassing) position or situation. When the boss started firing questions at me, I was caught with my pants down and looked like a fool. I just hadn't considered all of those potential outcomes yet and didn't know what to say! We seriously underestimated our opponents on Saturday and totally got caught with our pants down.
