When a person can't help but be nice, which makes them applauded by all but can be quite the inconvience.
"Sally is so unfortunetly kind. Did you know she said yes when Urkle asked her to prom? She's was probably thinking, Somebody get me the hell out of here."
When something so unfortunate and drastic happens that you'd think it would've been on television.
Ethan: I unfortunatelly thought the emergency escape door on the plane was the restroom and got sent flying out into the ocean.
Joey: I'll be damned. Sounds like a movie.
Ethan: Thats what I said! Unfortunatelly!
When someone engages in a bad act, but they want the person they fucked over to be grateful. Best known example is the deposition of Donald Trump in the case of E. Jean Carroll where the former president explains that he and other celebrities, or "stars," have been grabbing pussies without permission for millennia.
Josey: Carl, did you just eat the entire bucket of popcorn chicken that I brought for lunch and put in the fridge with my name on it?
Carl (imitating the 45th President of the United States): I did, in fact, eat all of the popcorn chicken unfortunately, or fortunately. *rubs tummy*
Girl 1: What does that mean?
Girl 2: it means it's unfortunate that he's sexuallt attracted to women but doesn't care about their interests and only views them as an object to satisfy sexual needs and to cater to his every whim.
