One of the unique aspects of living in Yemen is chewing qat, the tender young leaves of the shrub Catha edulis. In the late afternoon Yemenis often get together with their supply of qat, a water-pipe (narghila) and plastic bottles of spring water. Much has written about the plant and its use. For starters, check out the Qatalog on Yemen Webdate.
Youtube now brings you rap versions by Yemeni artists. Chew on this or this for awhile.
