When someone game of throne'd it, it means they skipped a few steps and went right to the finish.
A reference to the controversial season 8 finale of the American fantasy drama television series created by David Benioff and D. B. Weiss, based on the
epic fantasy novel series A Song of
Ice and Fire by
George R.R. Martin, where the producers infamously skipped a few step and went right to the finish, rushing near decade long character developments and arguably ruining the series finale of the most
epic fantasy drama television series of all time.
