obligastory
A story you have to listen to because if you don't, the person telling it will insult you and possibly throw something at you.
My friend told me the same story about his car again. I had to listen or he'd call me a dummy and throw a shoe at me.
My girlfriend told me about her ex again. I had to smile or she'd say I was a jerk and throw a pillow at me.
My mom told me the same tale again. I had to nod or she'd say I was lazy and throw a dish at me.
