Even after opening the link I couldn't shake the feeling it had something to do with that awful Mmm Mmm Mmm Mmm song from Crash Test Dummies, I hated that song and I hate this app even though they are evidently not connected after all.
Speaking of music, this app's name made me think of the album MMHMM by Relient K, which has a hidden track also called MMHMM (at the beginning of the CD).
