@HyL I guess the reason why that usage irks me a bit is that it's the opposite of the meaning of the same word in Dutch. In Dutch, the term is very clearly NEVER an identity, because EVERYONE is a 'fietser' sometimes. You'd never, ever use it as a part of your name or in your profile, and if you called yourself that in a conversation, people would look at you sideways. And I've frankly always LIKED that about the term--it's something so everyday and ordinary that making it an identity is odd.
