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. In fact, many of them have their “roll-ons” (township argot for mistresses; you know, you put your roll-on under your armpit. Get it?).» —“Envy is a very deadly sin” by Fred Khumalo The Times (Johannesburg, Gauteng, South Africa) May 17, 2009. (source: Double-Tongued Dictionary)
