obligastory
A story you're stuck with because if you don't listen, the person telling it will act like you're the worst friend or lover ever and possibly throw a fit.
My buddy told me the same story about his dog again. I had to listen or he'd throw a fit and say I was the worst friend ever.
My girlfriend told me about her ex again. I had to smile or she'd throw a fit and say I was a terrible lover.
My mom told me the same tale again. I had to nod or she'd throw a fit and say I was the worst kid ever.
