You want to optimize for highest finger replacement, ensuring that hands must change positions as many times as possible. Requiring shift-number row and then alternating in letter "z" would require a lot of that. Similarly, letters y g b and h are out of most people's home row, and requiring them to be capitalized would require the use of both hands.
Depending on the disposition of the individual a political, religious, or misspelled phrase (or multiple of these) could further inflame the password. Something like "their isa godd".
I hope this person deserves this.
