Why thiagobrandam ?
My full name is Thiago Brandão Damasceno. 13-year-old me thought it was clever to pick a subset of each name (thiago+bran+dam) and use it as nickname. Turns out thiagobrandam is a lot like thiago brandão in pt-br, so not such a good idea after all. But by the time I realized it, I'd been using it in all sorts of places (emails, websites, ...) and already built an online persona around it (albeit almost non-existent) and now I'm stuck with it :)
