A situation whereby rules are not observed by one party, so other parties feel free to ignore thier pledges to follow the rules. Actually happened with the real geneva convention.
Because we had some young kids playing they said 'no fucking' at the camp. John protested against this from the beggining and fucked everyone senseless. The other guys wanted pussy too, so the rules just became a genva convention.
American toilet paper.
Barack Obama: Shit, the White House is all out of TP.
George W. Bush: Ever tried the GENEVA CONVENTION? It's real good stuff.
Barack Obama: Thanks! Where'd you find this?
George W. Bush: I used it to wipe my tushy every day when I was in the White House. See how good it turned out?
