In the agency where I completed my apprenticeship as a graphic designer, we had our own beer, 

which we rebranded every year. 

My thought in this design was the following: People usually have some inhibitions when it comes to getting to know each other better, for example at an event. So what does it help to break the ice? Exactly! A beer. Beer doesn't only help to break the ice, no, it can also create real friendships and that's how I came up with the name BFF which actually means nothing else than "best friends forever". In short, beer brings people together.
