look up any word, like wcw:
A fiery temptress who is utterly brilliant, beautiful and smart. She is strong willed but will be a softie when you get to know her. She is awful at maths and loves nothing more than to lounge about in a reindeer onsie. She is funny, witty and knows how to get her own way. Always sexy and seductive in the bedroom but a cutie out of it.
Look at that Beffy, shes a complete #GingerNinja

Your best friend. Your closest bro. Your greatest mate.

A derivative of BFF: Best Friends Forever. Hence, beffy.
(sung) You're my beffy, my very best friend. Beffy, friends till the ends.
