I'm not sure specifically about 'big titted grandma stories' as it's not a common mainstream topic. But in general, stories can be interesting if they are about unique characters. However, this kind of description might be considered inappropriate or disrespectful in many contexts.
Well, we can focus on the grandma's character traits like her love and care.

Well, in grandma stories, 'big hangers' could be something like large clothes hangers that might have a special significance in the story. Maybe they were used to hang important garments or had some sort of magical property. For example, if the story was about a princess, the big hangers could be where her beautiful gowns were hung, and perhaps they were enchanted to protect the dresses from any harm.
Educate yourself on proper language use. Know what is considered inappropriate in different contexts. Replace offensive words with neutral or positive ones. For instance, if it's about a character, describe their good qualities instead of using disrespectful terms.
Once upon a time, there was a little girl named Lily. She visited her grandma's old house. In the attic, there were these big hangers. Grandma told her that those hangers were used by her great - grandmother. They were so big because they were used to hang the elaborate ball gowns that the family used to wear to grand parties long ago. These big hangers held the memories of those glamorous nights, and every time Lily looked at them, she could almost see the women in their beautiful gowns twirling around at the parties.
