Firthing is the act of hanging around the object of your affections looking intense but never actually telling them how you feel. The term is named for Colin Firth who played Mr. Darcy in a film adaption of Pride and Prejudice and spent a lot of time "firthing."
Rather than just tell her crush how she felt, Rebecca chose instead to spend the entire party firthing in his general vicinity.
Farah is the name of a beautiful girl. she is also kind and smart. She tends to be shy at times and was even reffered to as "fluffen" at one point. Without Farah there is no light in the world.
