Oy Kay

A combination of Oy vey (Yiddish) and okay.
Oy kay is when you finally agree to something, but you still complain about agreeing to it.

After a heated debate, Rabbi Weisman had had enough of Moshe's arguments and finally gave in, exclaiming "Oy kay Moshe, Oy kay, you win! You didn't win fair, but you win."
