Disobeying and doing something you belive is right even though it isn't legal. Comes from the Clash song of the same name, which was about playing rock music even though it was banned by the Ayatollah

Also, this was the first rock song played in Iran in ten years after the Shah was removed from his trone. It was played by on the American Army radio and became an anthem for the army during the first Gulf War.

Something the shareef really doesn't like.
'Shareef don't like it, rockin' the casbah. Rock the Casbah."

A shot containing 1/2 Southern Comfort, 1/2 RedBull, with a splash of Apple Puckers. Originated in Houston TX, this concoction must only be made with the right amount of each ingredient, or the Casbah will not be rocked. When made correctly, the shot is like pouring liquid deliciousness into your face. Immediately after consumption, you will completely lose control. Some will hit the dance floor, others will start a fight, and some will take their shirt off and show their nipples to the bartender. Who knows? Whatever the case may be, you will wake up the next morning saying, "things got a little weird last night." I should tell you to drink Casbah shots responsibly, but that is just not a possibility. The Casbah can only be rocked to the fullest extent.
I'm not gonna lie, things got a little weird last night. We bought a round of 16 Casbah shots at the bar, next thing I know I woke up this morning in the hot tub with all my clothes on and a dead hooker floating next to me. Let's Rock that muther fuckin Casbah again tonight son!

Get the Casbah Shot mug.
The Clash song also makes references to the cordoned off Arab areas of European colonial holdings. Rock the Casbah has been said to be a reference to the anti-imperialist movements in colonial nations as well as the banning of music in Persian and Arab nations.
Rock the Casbah = The Casbah in Algiers during the time that France occupied Algeria.

A song created by the Clash that has multiple meaning when looking at the song. Only reason the 2 guys definitions before this probalbly got it from "The Simpsons."
The shareef don't like it
Rockin' the Casbah
Rock the Casbah
The shareef don't like it
Rockin' the Casbah
Rock the Casbah

By order of the prophet
We ban that boogie sound
Degenerate the faithful
With that crazy Casbah sound
But the Bedouin they brought out
The electric camel drum
The local guitar picker
Got his guitar picking thumb
As soon as the shareef
Had cleared the square
They began to wail

In response to Iran's Ayatollah Ruhollah Khomeini (24 September 1902 – 3 June 1989) banning all music from Iranian radio and television in July 1979, the British band The Clash made this song as their protest against it. Ayatollah Ruhollah Khomeini is of the islam religion, which dictates to its muslim followers intense hatred to all infidels (aka nonbelievers).
The Clash did in-fact Rock the Casbah to islam's disapproval.
