A Derp
When you're being scared and coughing so hard it feels like your insides are coming out.
I got stuck in a closet and I became a Derp. I was scared and coughing like a dragon.
I had to give a speech and I became a Derp. I was scared and coughing like a robot.
I saw a ghost and I became a Derp. I was scared and coughing like a maniac.
