Well, I've explained this a few times before, but since you asked, I'm willing to share it again. My user name, sig, and avatar all go together for the same effect.

In Star Wars lore, Carrie Fisher was not allowed to wear a bra as Princess Leia, so her breasts were bound with gaffer tape. I thought that was pretty cool and funny and would be a pretty good name and it was probably something that no one else had used. So there you go. I'm Gaffer Tape. And I'm a theatre major, so I encounter gaffer tape quite frequently. So it's only a cool name when I'm here.
