Would you rather watch Borat or have a root canal? If a hypnotist asks for volunteers, are you suddenly keen to check out the restrooms? Did Rowan Atkinson's Mr. Bean leave you desperately needing to get out of the room?
If you answered, "Um... Not sure, really," "yes," and "yes," you may have an embarrassment squick!
(Or perhaps you're indecisive, and have a small bladder, but we can't really help you with that.)
