Semi-friends are guys that you meet on a regular basis, because you share the same group of people. For instance, the people you met after you joined a sports-club or a fraternity could be your semi-friends. The reason why you meet these people is often different from just hanging out together. a semi-friendship might also be called an arranged friendship.
Friso is one of my semi-friends. We sometimes meet in a bar, but he didn't invite me to his house-warming BBQ.
