This is a term used in frantic excitement, a high quaility version of the term LMFAO. There is nothing higher than this term when it comes to online laughing.
Your key strokes are always one key left because you're having an orgasm of laughter. This is how KNAFI is born.
You'll know you said something that's funny when someone uses this term.
Also this is a very common lebaneses cheese pastry.
1 lb phyllo dough
1/2 lb butter, melted
2 lbs ricotta cheese
1/2 cup pine nuts
3 cups sugar
1 teaspoon lemon juice (fresh).
"The kids are getting off at three, maybe I'll make a knafi desert."
