Together with his friends, he spends his time drinking, harassing black and Jewish kids, and looking for sex with loose local girls and with prostitutes.
When confronted by his father, Studs runs away from home, and makes a comically inept attempt at armed robbery.
During a neighborhood football game, he is repeatedly flattened by a Jewish player on the opposing team, and he is easily defeated during an amateur boxing match at the park.
Nonetheless, Studs constantly reminds himself and others about the time he bested "Weary" Reilly in a streetcorner fight when they were kids.
Studs' father sells their home, and the Lonigans move to a new apartment building in South Chicago.
And now, he clearly isn't even a tough guy- just a fat alcoholic who is scorned by the rough crowd whose respect he wanted so desperately.
