Can I set a 'nuke' password for an encrypted secondary drive?

I have an encrypted 2TB HDD, and I would like to be able to enter a password at the decrypt step of mounting it, that will render the drive un-decryptable. I have seen a few article online about this but I don't know how to go about doing this. I am hoping someone else on here has already done this sort of thing.

I am using Ubuntu 14.04, and I can wipe the drive if I have to, as it isn't holding anything important right now.
