A fatty of fun
A fatty of fun is when you’re so messed up you can’t even walk straight and still manage to make everyone around you laugh like it’s the best joke ever.
I had a fatty of fun at the park. I fell over three times and still managed to laugh like I just won a million dollars.
My friend had a fatty of fun at the mall. He tripped over his own feet and started laughing like he just discovered pizza.
I had a fatty of fun at the grocery store. I walked in backwards, dropped a carton of eggs, and still laughed like I was the king of the world.
