The Loud Jerk was a bully who lived in New York City.
In 1941, during World War II, the loud jerk attended a local cinema and watched an advert which had been showing the different ways soldiers and civilians can help with the war effort. The guy thought it was boring and began to yell at the screen. When Steve Rogers, who was sitting behind him, told him to be queit, he stood up and took Rogers outside to an alley where he began to beat him up. Rogers tried to fight back, but the jerk continued to overpower him. Eventually Roger's friend Bucky Barnes arrived. Barnes helped Rogers and beat the jerk up himself.
