Closet princess

A man who thinks he is perfect, big, tough, or any combination of these, but panics at the sight of his own shadow.

"Jonathan, my neighbor, is a closet princess - he acts tough like he's 2Pac, but you come out the bushes on him and he screams like a 4 year old girl and runs away. Yesterday I saw him take out the trash and he looked down on the ground and jumped, dude literally got scared of his own damn shadow."
