Typically, an middle aged man whose butt has grown sideways versus outward. A dad butt can typically be found in khakis with pleats. The largeness will only be found in viewing from behind and not a sideways glance.

Dad Butter 

Large pats of butter on any kind of bread. Usually deemed gross to us as children but, somehow is delicious as an adult. Preferably salted butter to appreciate the sweet / savory combination.

Hey, “grab me a piece of toasted bread with some Dad Butter please.”
