Fefinitely

"Fefinitely" when a drunk person confirms their plans to meet in the future but won't remember anything tomorrow.

Yeah, he said he will fefinitely call me tomorrow. I even had to write my number on his belly, but but I doubt he will remember.

Fedinitely

complete certainty; without doubt; a term that is used for emphasis
also known as "fed" for short

I fedinitely just typed "def" into my phone and it auto-corrected to "fed," thus making "fedinitely" a word.
