A very common and widespread use of the word “Al-Qaeda” in different Arab countries in the public language is for the toilet bowl. This name comes from the Arabic verb “Qa'ada” which mean “to sit”, pertinently, on the “Toilet Bowl”. In most Arabs homes there are two kinds of toilets: “Al-Qaeda” also called the "Hamam Franji" or foreign toilet, and "Hamam Arabi" or “Arab toilet” which is a hole in the ground.
