Upset, Shocked, In disbelief, frustrated, RATTLLEDDD!

Usually occurs when something happens a person did not expect or can't believe happened.
When someone gets rattled be sure to call them out on it, usually receiving a response similar or equal to: I'm not rattled!

Yelling rattled in the person's face or shaking your hand back and forth adds to the effect.
