A rowdy drunk young man is often referred to as a "lout" or a "ruffian." Colloquially, terms like "party animal" or "rowdy" might also be used to describe such behavior. In more informal contexts, you might hear terms like "drunken fool" or "wild spirit."
One example of characterization in The Jungle is the description of Jurgis as a strong and hardworking man who is determined to provide for his family. Another example is the portrayal of Ona as a young and naive woman who struggles to survive in the harsh conditions of the meatpacking industry. Both characters are depicted through their actions, dialogue, and interactions with other characters in the novel.

If this young man really likes you then wait and see if he gets in touch with you. If he does not contact you then you could either talk to your best friend about it to find out if this young man is shy or he just isn't interested in you.
