BYMFIIT

Abbreviation for "but you may find it informative too" (or "but you may find it interesting too"); typically used after FMI (for my information).

FMI (BYMFIIT), I just discovered that you can add your own definitions to Urban Dictionary so other people can understand weird new abbreviations you come up with.
