dad slice
A dad slice is when you take the biggest chunk of cake or pie like you're the only one who deserves it and you don't care if everyone else gets crumbs.
My dad took the dad slice and left me with a tiny sliver. I had to eat the crust.
At the birthday party, my dad took the dad slice and said, 'This is my piece, deal with it.'
My mom said, 'You took the dad slice again, I'm not even mad.' She was lying.
