I refer to Rapeseed Oil as Sexual Assault Oil.

It is very common in Europe, but I've never seen it in any store in the US.

You Americans are so funny. Rapeseed is a perfectly correct name for this plant and I honestly don't think we consider it offensive in the slightest. I think it was in Canada that the euphemism 'canola' was invented for rapeseed oil. The word rape has two different etymological roots:
rape (n.1)
early 14c., "booty, prey;" mid-14c., "forceful seizure, act of snatching by force; plundering, robbery, extortion," from Anglo-French rap, rape, and directly from Latin rapere "seize" (see
rape (v.)). Meaning "act of abducting a woman or sexually violating her or both" is from early 15c. Late 13c. in Anglo-Latin (rapum).
rape (n.2)
kind of cruciferous plant (Brassica napus), late 14c., from Old French rape and directly from Latin rapa, rapum "turnip," which is cognate with Greek hrapys "rape," Old Church Slavonic repa, Lithuanian ropė, Middle Dutch roeve, Old High German ruoba, German Rübe "rape, turnip," perhaps a common borrowing from a non-IE word (de Vaan).
