You could transpose the word in some way. So maybe move each letter two keys to the right - 'p' becomes ']', 'a' is 'd' and so on. They you end up with ']di]dl' instead of 'paypal', which is a bit more obscure. It might not work so well if the rest of your passphrase is made up of dictionary words.

I'm a bit paranoid though - most compromises aren't targeted and if a hacker gets a list of 20,000 hashes to crack they aren't going to inspect them individually.
