Take an initialism (D.F.T.B.A. - don't forget to be awesome) or an acronym (P.I.G. -pie is good) and use the last letters of each word to make a new initialism/acronym. Charles and Sue will demonstrate.
Charles:(D.F.T.B.A.) Don't Forget To Be Awesome
Sue:(T.T.O.E.E.) Time Travel Obviously Explained Enough
Charles:(E.L.Y.D.H.) Even Love You Don't Have
It can be a bit of a mental exercise but I think its fun.
To kick it off I think it would be awesome to use your favorite version of D.F.T.B.A. rather than have me pick something boring and stuffy.
