This is meant as an example only, to help you choose a password that is unique and difficult to guess. Do not use this example as your password.
Suppose your favorite ice cream sundae is mint chocolate chip with whipped cream and a cherry on top. You could create a password like this:
mCC = mint chocolate chip
wc = whipped cream
1c = one cherry
! = favorite
Notice how we added security by using capital letters for the chocolate chip reference. Putting all of these characters together makes no sense to anyone else, but would be easy for you to remember.
