جرجير = gargeer = arugula = rocket

Anyway you say it, this is one delicious leafy green.

Arugula (known as gargeer in Egypt) is a mighty potent leafy green. Spicy. Flavorful. Filled with antioxidants, vitamins and minerals.

Gargeer is plentiful everywhere here in Cairo.
Gargeer gives virility. In Egypt, it is often referred to as viagra.

There is a saying in Egypt:  سرجرجير  تحت السرير
which means if a woman would know what arugula could do for her man, she would grow it under the bed.

The words in Arabic creates a rhyme:  "Lau maratuk errfet serr il gargeer, la zarito tat el sareer." If the wife knew the secret of arugla, she would plant it under the bed. Gargeer (arugula) tat (under) el sareer (the bed).
