answer:It definitely happens in the US, but it’s not everywhere all the time. A bunch of young men together, or male teens, is generally a little scary. I would avoid them if I were walking down the street. When they are in a public place and being loud or destructive it’s awful. My experience is most young men are just fine, but you just never know, once they are in groups it can go bad. Even a group of girls can go bad, but less likely. Like I said it partly depends where I am. On the streets of Memphis I’d be more paranoid than in a restaurant in Boca Raton, FL. However, even when I worked in a mall in Boca (Boca is a very affluent city in Florida) if a bunch of guys walked in wearing baggy clothes I’d call security.
