When you find out that the person you thought was a dude or a chick turns out to be the opposite. You find out they have a vagina instead of a penis. Therefore, you get a tranny suprise.
Vitale wouldnt show his dick so mary was getting a little worried. She caught him buck naked in the shower and finally saw why he was so secretive and abnormal about showing his dick. He had a little 'tranny surprise' downstairs.
