Waxay noqon karaan qaabab iyo cabbirro kala duwan waxayna u ekaan karaan dhibco madow oo yaryar, yar yar, dhibco hadh leh, baro waaweyn oo daruur u eg, xargo dhaadheer oo cidhiidhi ah. Bukaan-socodka ayaa laga yaabaa in badan oo sabeynayay yar yar ee beertooda aragga ama hal ama laba ka weyn oo keliya. Badbaadiyayaashu waa kuwa yaryar oo si degdeg ah uga guuraan goobta aragga.
