FedExcellent

The irrational euphoria people get just from opening surprise packages, no matter what's in them.

Man, ripping open that box felt FedExcellent, but turns out it was just some junk I left at my ex's place.

fexcellent 

A corruption of the phrase "fucking excellent".

Allows usage in situations where the word fuck would otherwise be inappropriate.

Also used in public forums where users have grown tired of the simplistic nature of "fuck"

Dude, that is fexcellent.
