dad butt
A dad butt is when a man’s butt is so wide, it could probably be used as a doorstop. You only notice it when you’re walking behind him in the grocery store.
I walked behind my dad and I swear his butt was trying to block the entire aisle.
My dad’s butt is like a burger, it’s always full and never cooked properly.
I saw my dad’s butt and I almost started crying.
