roll-on
n.— «I also know that many white brothers who raise issues with Msholozi’s polygamous ways are not necessarily opposed to the notion of having two or three wives.

Get it?).» —“Envy is a very deadly sin” by Fred Khumalo The Times (Johannesburg, Gauteng, South Africa) May 17, 2009. (source: Double-Tongued Dictionary)
