Convergent evolution due to similar environmental pressures, I presume :) Garbage is a collective noun in Russian and can't have a plural, but in thief jargon it's used as a singular noun for one cop (the garbage is on my tail), and, hilariously enough, in a plural for multiple cops ("garbages were whistling all night in the park", it's from a song).
