RussianАвосьBlind trust in sheer luck; counting on a miracle.

This word is ingrained into Russian mentality. All those videos with Russians doing crazy stuff - they are thinking "Авось пронесёт", "It has a chance of succeeding, so I will count on it." Another thing is "[avoska](https://en.wikipedia.org/wiki/String_bag)" - string bag that you carry in your pocket just in case you can buy some deficit goods.
