nice use of the term; however, I have said umfriend when mainly introducing someone I don't consider myself to be really friends with, but more of an acquaintance. This is usually because I find my definition of a friend is usually a little more strict and requires more than most people so whom I consider to be acquaintances oftentimes consider me their friends.. So when introducing I say ....um...friend. Or just leave out all things and just say there name
I do like it in this context though.. very appropriate, i just wish I had an umfriend right now
