Textbooks will not teach you these and you will hear them within an hour of arriving. Everything on this page is ordinary informal speech rather than anything coarse, but it is the register of friends and the street, not of your wife's grandmother.
A warning worth taking seriously: slang moves fast and it moves regionally. Something current in Algiers may sound dated or simply odd in Oran. When in doubt, listen before you use it.
