A title for an attractive mature woman or MILF from a foreign country who is not too familiar with the native language and is easy to trick into having sex by comforting them. They usually have a very tight, sweet tasting pussy by definiton, hence "Loon N Fabby" for loony as in different, yet still fabulous.
Natalia from Russia suddenly moved to the United States to live with distant family when her parents died. At the airport a "gentleman" named Stephen offered her help in finding her luggage. Since she was uncomfortable she quickly became friends with this kind stranger. Things rolled quickly and before you know it, things were loon n fabby for both of them.

An ultra-peaceful Claude Debussy composition that pays homage to everyone's favorite feathered ululating pond-drifter.
If I listen to Debussy's dreamy "Clair De Loon" and Saint-Saens' soothing "The Swan" one right after the other, I wonder if I will be able to stay awake.... not only do I love the slow soft tones of said compositions, but thinking about those two types of stately slow-swimming water-fowl always makes me drowsy.

A person who likes to screw over other people for his own twisted pleasure and would even sell out his benefactor for 30 silvers. He is the human embodiment of Sinkiephus, Lord of Pwning and sleeping well at night.
"Damn, I got pwned hard today."
"Must be a sze loon."
"How did you know?"
"He is sleeping well tonight."
"Must be a sze loon."
"How did you know?"
"He is sleeping well tonight."

Charles was scrolling Facebook the other day and stumbled on Bob's new profile picture, which looked absolutely nothing like him. "What the F is that and who am I looking at?" Charles exclaimed. "Bobby is totally unrecognizable and a little bit nuts. IRL he looks like a high-school janitor but on Facebook he's a supermodel! Bob is definitely a Filter Loon." Charles logged off and went for a walk.
