2.
1.) Some random guy who won't wave to you on the street, or otherwise greet you.
2.) A man who does you wrong/screws you over
3.) An especially bad driver

While usable for all genders and ages, the preferred word when talking to a woman is "lady" (lay-day).
When a child is the target: "junior" (joon-ya) is appropriate.
Ayyy! Fuck you budday!!
