Student fraternities in Germany have elaborate coats of arms. The members of the “Weinheimer Seniorenconvent” have theirs displayed in the great hall of celebrations of the Wachenburg in Weinheim. Many of the mottos include friendship.
Personally, I don’t hold with the often rightwing positions of those traditional fraternities (somewhat ironic as many have their roots in the revolutionary times around 1830 with then revolutionary ideals) so I rather go with this:
It doesn’t have to be alcohol, just sit together and share a glass and a talk.
