I think that having this feeling of missing out, or going like "wow that was for just a little" like when you team misses a goal, is one thing
but being grumpy and sad or angry about it, and putting everyone around us in a bad mood because of our feelings is a different thing
many levels of complaining maybe
I agree that losing makes us appreciate winning more, the same way as sad makes us appreciate happiness more too
Yeah, at the end of the day it is our own responsibility to stop before it's too late.
Many people get frustrated when they lose and start blaming anyone else but themselves.
I think it's fair to say that the behavior you are describing is the most popular. It's not a good one though.
