No one deserves to be bullied, no matter what their actions are. Perhaps reprimanded, chastised, and/or corrected, but never bullied. I was bullied in elementary and middle school, and there was nothing that I did that justified it. You may need to do some research on what bullying is, what kind of people are targeted, and why people get bullied in the first place.
In your first example, the guy just sounds like your stereotypical douche that can easily be ignored, since it seems to me that he was probably joking most of the time and whatever friends he had understood that, but you apparently didn't.
Your second example sounds like a person who would get targeted by bullies anyways, but at the same time sounds like he didn't have an ideal home life and that there was some major financial trouble. He probably got his clothes from somewhere like the Salvation Army or something if his pants were often too big and he didn't usually wear underpants.
You are honestly being very unfair to the people in your examples, and I honestly hope you aren't anything like that IRL.
