look up any word, like tribbing:
similar to happily, commonly found in the phrase "happily ever after", except in the case of the word "haffily" everyone doesn't live happily every after, they are killed by being cut in half, thus the origin of the word haffily.
-"dude all the guys in Sweeny Todd lived haffily ever after!"
-"i know right! That was the goriest movie ever!!"
