My tag is actually a compromise, because my original idea was too long. Basically, at sixth form, my nickname ended up being Virgin Destroyer, for obvious reasons. It has always stuck, so everything electronic I can give a name, is called Virgin Destroyer. Like my PC, the bluetooth name for my phone, everything. It was going to be my gamertag, but it was two characters too long and I hate misspelled tags, so I thought I'd go for Vice Destroyer. Pronounced in a very deep, gravely "american cinema advert" voice. I settled for Vice, because my first name is Victor and because it keeps the inherent insult that my friends came up with when you look at my tags initials.
Just a little in-joke for me, I suppose.
