Mmkay. (Keep in mind I've had this username since.....2005 I think.)
When I was little (And in Girl Scouts) we went to camp at Camp WoHeLo. Me and A Few other girls had this club on the top bunks, and had nicknames and passwards and all that jazz. That day I was wearing a shirt from the show 'Zoom' (I was never on the show, my mom found the shirt at Frenchy's XD) and while we were deciding our nicknames, I was sort of hyper, so I decided on Zoom. So when I got on to Tamatalk and went to create my username, I L-O-V-E-D the show Zoom at the time, so along with my nickname from camp I chose ZOOMrocks. Tada!
P.S. Sorry for such a long story, thought I should fully inform those of you that care XD.
