When you and your husband/wife/bf/gf say or type the exact same thing at/roughly the same time. It is not a Mfeo Moment unless you love the person you do it with more than ANYONE else. If you do it, it just shows how strong the bond is between you two.
Person 1: I love you so much...(11:37:37 PM)
Person 2: I love you so much...(11:37:38 PM)
Person 1: mfeo moment :) (11:37:45 PM)
Person 2: mfeo moment :D (11:37:46 PM)
*Epic mfeo win*
Very similar to mfeo, (made for each other), but adds the extra component of difficulty in that there is a large distance between you and your "made for". Thus, your mffeobtffa is made for each other but too f-ing far away...
