I'm not a native English speaker, but i think you'll understand me. I've recently seen a billboard that had a word like "effei" in it, so I googled it. The effei seems to stand for European Federation of Financial Executives Institutes, but also, I've found this link:
Effei is a beautiful person in body and soul. Effei is seen as weird and different before truely getting to know her but she is someone you would rather have as a friend than an enemy. When Effei is in live she will give it all to the person of interest. Effei will always put her friends before herself making her the ideal listener.
Effei wanted to go on a date with her boyfriend but her friend needed advice so she had to stay and help
So, my questions are: Does this word exist in English? If not, could it be from another language, or is it just a made up word? If, again, not, is there an English word that encapsulates the described person? If not in English, is there a, lets say, a Latin word for it? Note that I said "Latin" instead of "any other language", and by "Latin" I mean: Any phrase/name/synonym for that kind of a person.
