The only betting I like is to show commitment to your stated position. I’ve made serious proposals to fuckwits running their mouths online. Running your mouth is free. Put some money on it if you believe in yourself. Unsurprisingly, I’ve never had a taker.
Otherwise, sports is boring as shit, and gambling is boring as shit. I went to a casino once cause I was close to one with my mother, and she really wanted to go. I was fucking miserable. An opulent cathedral to boredom and sadness.
