Welcome to BB, owa. And you're a VHer! I'm so glad for that. 🙂
And I'm also 20-years-old university students. *bitter laughing*
And what does your username mean? The only thing I think is, some singers from rock bands singing "Owa a a a!!"(Do you know the band Disturbed? 😀)
In Final Fantasy VII there was a song for the final boss fight and it was titled "One Winged Angel". That was the username I would use when signing up for boards and playing games online...
At a certain point, I matured and thought the name was horrifyingly lame (it was, but I was 10 or 11 so cut me some slack!), and I just went with 'owa' because it was super easy to remember, haha, and it wasn't embarassing 😛
I do know of Disturbed though.
