"The water pipe made of a small calabash with a hollow reed on which a small clay bowl is placed, which is mostly used for the purpose in this area, goes round from mouth to mouth among gatherings of either men or women."

Studien zur Afrikanischen Geschichte Bd. 6, LIT Verlag. 1992) "..the "mutopa", as soon as its owner takes the first puff, runs from mouth to mouth without distinction of classes, and when it returns to him and if he still has a piece of tobacco, he has to add it in order to take a new puff and let it go round again...(rif.Dias de Carvalho 1890: 677 Northern Chokwe/Lunda)
