There is a pseudo system I use for brainstorming ideas and it simply starts with a letter from the alphabet. :)
Every few weeks or so, I grab a yellow pad or whatever text editor on my phone/laptop, and write each letter of the alphabet on it's own line.
Then a few days later, I'll go through the list and come up with a title for each letter. A week or so after that, I'll jot down a logline, theme, or idea for the titles.
Give it a try. It works for me. Ironically, the more the story ideas/concepts get developed, the title ends up changing.
