family feuds

Family feuds are prolonged conflicts between relatives, often spanning generations and involving grudges, inheritance disputes, or perceived slights that compound over time.

The phrase suggests something more entrenched than ordinary family arguments—old grievances that resurface at holidays, estrangements that divide siblings for decades: The family feud over Grandma's estate lasted twenty years.

The term also names the long-running game show where families compete to guess popular survey responses.
