Golf is more of a US euphemism for connectedness/social shared sports, could be anything really - basketball, racketball, softball, whatever.

As for low level... I guess you have never lived in smaller cities/towns in Europe then. People know each other and afford those they know “courtesy” of a heads up. Word spreads, etc. From there, you are only one step away from someone retaliating against you. The kicker is that those involved might not even really understand this to be somewhat corrupt behavior.
