A band kid is the most hardworking, empathetic, caring, and driven person you've ever met. They will put aside their own concerns to make sure you are not only welcome in the program but also that you are completely taken care of at all times.
Jacob made sure I had a place to sit at lunch today AND he helped me with my math homework, he must be a band kid!
A phrase used to warn others (friends etc) that they have attracted a stalker. A stalker alert without having to mention the words stalker in front of a stalker.
I'm out at a club and my best friend has some 40 year old sleaze bag hovering over her. So I say "wanna see a band" and she replies "yeah let's get the f*ck out of here"
