A boy who is utterly obsessed with the band All Time Low.

This boy knows all their songs, all the background information about the band, and could possibly have a picture of the band as his phone background/have one of their songs as her ringtone.
Chris: DUDE, I LOVE ALL TIME LOW SO MUCH!!! I NEED TO SEE THEM IN CONCERT!!!
Lilly: What an All Time Bro you are, Chris.
