GR translation: It isn’t politics or fuck-your-buddy

[Mike Jing]

V331.19-27, P336.13-21   . . . . Geli snickering in the darkness. They
must have known her. They didn’t ask her anything.
       When he brought it up later, she wasn’t sure just what this is
between Tchitcherine and the Africans, but whatever it is it’s being
carried on with high passion.
       “It’s hate, all right,” she said. “Stupid, stupid—The war’s
over. It isn’t politics or fuck-your-buddy, it’s old-time, pure,
personal hate.”
       “Enzian?”
       “I think so.”

What kind of sentiment does "fuck-your-buddy" imply here?
