Children's bets like: you can't do it (any random action within the context and environment), I'll bet my salary...
If the bettor has bet something... be it money or some personal item, is the bettor obliged to pay? What does your jurisdiction say about this?
But now, what if a person bets something in a joking tone (e.g. betting on his salary) and a conversation that was supposed to be a joke ends up becoming hysteria, where the man may have said that because he was drunk or was naturally exalted due to the heat of the moment... remembering that in this example, he bet his salary, and if he won he would not win anything from the person he bet against (he just wouldn't give the salary to the opponent who would receive the bet...), can the person who would "win" the bet force the friend who made this childish bet?
Have you ever made a bet that led to an embarrassing situation or do you know someone who has?
What are the limits of a bet, can a bettor bet something that he is unable to pay? i.g: betting your own life or 10 years' salary? And also without gaining anything in return, since he only bet against and didn't bet anything if that bettor won...
Or as long as everything was done in a contract that such unusual types of bets would be worth?
You can use as a source of argument, this news that I will leave linked here.
In the examples below, the news that a man bet that he would take the virginity of a religious woman, ended up marrying her because he fell in love in the process, but a friend let it slip that this was the result of a bet between co-workers, the what do you think about that?

I think this is the result of human stupidity. Sometimes people get themselves into difficult life situations and no one is to blame for this but them.
Regarding the man who eventually married this girl, I believe that this was the way. In the end, everything happened well and he found himself a wife, but everything could have turned out much worse. He could have caused a lot of pain to this girl.
About betting with friends, I had a bet with a friend for $100. I said that all Champions League finals are played only on Saturdays. I was sure of it. Before the bet itself, I decided to change the reward for winning from $100 to a simple chocolate bar so as not to spoil my relationship with my friend. I was sure that I would win. Imagine my surprise when I found out that Bayern and PSG played on Sunday in 2020. In the end, I lost the chocolate bar, not the $100. Conclusion: you should never get into an argument, but if you do, then be sure that you are right.
