And the thing itself (not a particular term for it) has rather different connotations in Egypt. Nasser, whose Revolutionary Command Council seized state power in 1952, remains tremendously popular. SCAF's 2011 deposition of Mubarak is remembered fondly by many as well, although maybe not as much as the Revolution now. Of course Egyptians faced with a military takeover are more likely to think of those examples than some bloodbath in Latin America.
But there is one intelligent argument against calling the ouster of Morsi a coup: that since the military, and the extensive state and commercial apparatus it controls, had never, since 1952, ceded power, they couldn't very well be said to seize it. (That was formulated by someone more clever than me, although I can't find the link right now.)
