your absolute best friend. Your nearest bro. Your greatest mate.A derivative of BFF: Best Friends Forever. Ergo, beffy. A fiery temptress who's utterly brilliant, breathtaking and smart. This woman is strong-willed but will undoubtedly be a softie when you are getting to know the girl. She actually is awful at maths and loves only to lounge about in a reindeer onsie. She is funny, witty and is able to get her own means. Constantly sexy and seductive in bed room but a cutie out of it.
