Lackingphobia
The terror of getting caught with nothing and/or messing up; getting busted doing something evil and/or totally messed up
My mom walked in while I was wearing pajamas and eating cereal at 11 PM. I had Lackingphobia for weeks.
He got caught sneaking pizza into the office after hours. Total Lackingphobia moment.
I forgot my homework and my teacher caught me. Lackingphobia hit me like a ton of bricks.
