Prat

“Prat“ means fool. Usage in a movie (“Lock, Stock and Two Smoking Barrels“): - You cannot make a cup of tea, Edward. - The entire British Empire was built on cups of tea. - Yeah, and look what happened to that. - And if you think I’m going to war without one, mate, you’re mistaken. - Going to war with what? Have you forgotten those guns, you dozy prat?
