WHat grinds my gears part (1)

hello everybody..let me tell you 1st what the HELl does "what grinds my gears" means..its something like food for thought etc etc.the only difference is that its on topics what i think abt(atleast for a min)..er..and also gears are there in cars and i worship cars so i preffered gears over food(for thoughts)..

You know what really grinds my gears....
the national anthem which is played at a begenning of every movie in bombay..yes every show of every movie..i really dont know what the hell is the governmet trying to do here,bring out some patriotism?yes(i know)...but through movies..cant they think of something better...
