1.
HFK
Only the most amazing thing in the world. There isn't anything in the world that could make you happier because this is the definition of happiness.

When I'm with you, I feel like the luckiest girl in the world to have the most amazing boyfriend standing next to me holding my hand. You're the best thing that could have happened to me, and I am extremely thankful to have you in my life. I love you.
HFK I miss you and I really hope that you don't have to go far away for dental school.

HFK
Something used to hide your face from a boy.
"Marcie, your prom dress is really pretty."
-->"Yeah, I even have a HFK attatched to hide from my date!"
"AWESOME!!"
