MFE 

MFE is short for "Most Fun Ever"
Can basically describe any event, situation, or moment in which one is having the best time of their life.

It can be used multiple times. One time you are having the MFE may not be as fun as the next time you have the MFE.

Katie: "I am so glad we came to Vegas for my Birthday!

mfeobtffa 

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...

MG: I think I finally met my soulmate!

MA: No way! Really? Then why do you look so sad?

MG: It's a case of mfeobtffa...

MA: That's why they make airplanes, silly!
