I was thinking about this thread -- and realized condom--was not the first association i had with rubber-- (nor was eraser)

sometimes i "burn rubber"-- take off in "jack rabbit" start, with tires squealing--(and leave those middle age men in their new sports cars to eat my dust-- I drive 5 on the floor-- and have driven stick for 30 years...I know how to pop the clutch and get my little 4 cylinder engine into gear...)
or tell someone "that where the rubber meets the road"-- the place where action replaces talk
or "lay down rubber"-- exit and put some distance between myself and whatever

and while i don't often play cards-- if i did-- it would be an other rubber of gin.

while rubber can =condom, more often "trojians"=condoms (a specific brand)
