Bézier moi
Fantastic article and well written, too. For those of you, like me, who don't know French and miss the pun of the title: https://en.wikipedia.org/wiki/Baise-moi.It also mentions the concept of the osculating circle, probably the only risque mathematical term (anyone know of any other ones?), which led me of the following poem (from this post https://motherboard.vice.com/en_us/article/ezvq9n/the-kissin...) that summarizes Descartes's Theorem (https://en.wikipedia.org/wiki/Descartes%27_theorem):  "For pairs of lips to kiss maybe 
  Involves no trigonometry. 
  This not so when four circles kiss 
  Each one the other three. 
  To bring this off the four must be 
  As three in one or one in three. 
  If one in three, beyond a doubt 
  Each gets three kisses from without. 
  If three in one, then is that one 
  Thrice kissed internally. "

EDIT: Turns out there are many other such math terms, e.g. see https://math.stackexchange.com/questions/1102872/unusual-mat...:
