To play on flick of the finger In high school as well as during military services and during several other occasions when young people play some games where there is a loser (like in card games) it is very common to PLAY ON SOMETHING. Like let's play On money. Play on something isn't a kind of set phrase it's just a verb and a preposition that is used in Ukrainian and Russian languages. So, let's say you play the game of cards where the loser receives flicks of the finger (see the video link) which are extremely painful. To suggest playing the game we say "let's play on finger flicks". The meaning is clear to every Russian-speaker - the person who loses the game needs to be flicked on by other participants. These games are pretty common for ex-USSR countries. They are the part of their culture. The flicks of the finger shouldn't necessarily be so painfull as they shown in the video. I have a language question here. Is the preposition correct in the sentences like 'Let's play ON money' or 'Let's play ON finger flicks'? What would be the most common way to suggest an English speaker to play ON something? These games are quite common especially when the guys in the gang are drunk and they don't have money to play on, so they start playing on finger flicks. This way the card game becomes very exciting and thrilling as nobody wants to lose (nobody wats to get flicked on like here in this video https://www.youtube.com/watch?v=62eSDZgC45I). P.S.: I am super interested in the language and in getting things right, so if some expressions are wrong in my description could you let me know (I still am not sure the finger flicking is the right word to describe the action in the video).
