The word "aspirin" for long was used as an euphemism for "condoms".
To speak about condoms was considered indecent. They were sold at the same place - drugstore, and in small paper packages, as aspirin. So, the word "aspirin" started to be used as an euphemism.
There was even an old anecdote about it:
An interview in the television study for a position of an announcer.
A guy with tic comes. He winks incessantly.
Everything is excellent, but they say:
-- Sorry, your tic could be a problem.
-- Oh, it is not a problem, one aspirin an I am OK.
The guy looks in pockets, pulls out several heaps of condoms, at last finds a package of aspirin, swallows it the tic stops and he passes all remaining tests.
-- You are fine, but we are a decent company and don't want to take such sexual aggressor.
-- You mean these condoms? Try to ask for an aspirin in a drugstore and wink!
