I beat the fuck outta you goofy
You tell a goofy you're gonna hit them so much their brain will come out of their ears.
You said, 'I'm gonna beat you up so hard your brain will come out.'
He said, 'I'm gonna punch you until you're not a goofy anymore.'
She said, 'You're the stupidest, I'm gonna beat you up till you're not funny.'
