It started as a joke, we used to laugh at the groups of guys who would gamble their food money doing "feast or famine"they knew it was dumb and so did we. Then the joke slowly moved over to my group of friends doing so and we knew it was dumb and treated it so. Fast forward 6 years and its so entrenched in daily life every single guy I know at least casually gambles weekly on their favorite sports and some do multiple bets per day on games they dont even watch. I bet $20-$50 on MMA which is like 5% of my income each week thats considered low.
