Simba Face
A face that shows complete and utter surprise, usually made after a statement delivered by someone else. Often the individual making the Simba Face cannot face the truth of the statement and so remains speechless. Named after Simba from the Lion King, due to his colorful facial expressions.
"Hey Frank, did you say the 'Simba Face' John made yesterday?"
"What happened?"
"Well, Mark told John he was screwing up the companys funding with his inane ideas, and he just gave him a total simba face in return"
