I really don't like this. Neither as a full name nor as a nickname. Sorry, it makes me think of tofu. Chris may be overused but it's still way better than Topher.
Reminds me of "tofurkey," a turkey-shaped tofu dish. Why not just use Chris? It's hardly overused anymore. Almost all the Chris's I know are well into their thirties/forties, with the youngest one being about 26.

This reminds me of tofu and gophers. Why not use the full name Christopher? Not many people go by it, which is such a shame as it's such a great name!
