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.

A 'beffie' is your best friend forever (BFF).
This person often provides for a reason to not kill yourself and continue living life.
Beffies often get well maggot together, and have mad times in Rottnest during Leavers.
"Look mate, i'm gonna have to ask you to not talk to my beffie like that, or i will fucking kill you."

"Dan Wilde and Ben Smith are mad beffies."

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

Mcd"s has gone surf and turf. Just smash a big mac and filet-o-fish. This by no means a health lover meal. It's so bad but so good and only 920 calories.
