I'd like to suggest using College Foot Ball slogans, if this person had been a College FB fan! Roll Tide, Crimson Tide, War Eagle, Fearless and True, Oregon Win the Day, Fighting Irish, Gig 'em Aggies - I found 52 here:

I'm also sure Pro teams have slogans that will bring on some smiles! You might also see if there was a team this person played for, was on the Pep Squad for etc. That little research might prove the best resource of all!
Good luck and thank you for doing this.
