Look in the profile or settings panel of your client to get your Tox ID which should look something like:
Yuk! I see this flaw so many products like this, just about anything p2p, blockchain addresses, commit ids, etc. I think there is zero chance of getting anyone who is not technology elite to adopt a product with UX that rotates around these untypeable/unpronounceable/immemorable identifiers. Why aren't Identicons(https://en.wikipedia.org/wiki/Identicon) or QR codes used more?
Human-meaningful: Meaningful and memorable (low-entropy) names are provided to the users.
Secure: Any entity in the system can act maliciously, including the majority of the entities or the available computational power.
Decentralized: There is still only one, unique and specific entity to which a name resolves.
Edit: Ah, I see; "including the majority of the entities" would exclude Namecoin from being a proper solution to Zooko's Triangle.
Nothing stops you from turning that hash into a QR code (afaik Antox does) - but then how do you copy & paste it?
