There is nothing surprising.
Russians watch lots of American movies/TV shows.
So many terms are being borrowed. This how the culture spreads.
Even though very few Russians would actually hold a sale in a garage due to the difference in housing between Russia and the US
I think he means the link will go to a page in Russian. Though the Russian term is indeed гаражная распродажа, which indeed just translates word-for-word to "garage sale"
Does this mean the Russian term is garage sale?
I’m amused that in the US we use that term too.
