Define coup please

I know I'm probably not as sharp as President Obama and his Sec State Hilliary but it seems to me that if a President is told by the Supreme Court of his country that something he wants to do is illegal and unconstitutional and he tries to do it anyway then in response the Court and Congress have him removed from office, that ain't a coup. That is the other coequal branches of government responding to a blatant power grab by a Chavez loving, scumbag emulating piece of trash. You're know by the trash you keep company with Prez.
