Machine Gun Huffing
When you're so amused by something that you let out a series of tiny, aggressive snorts through your nose, like you're trying to intimidate the person telling the joke.
I huffed at my dad like I was trying to fight him when he said, 'You can't just take the last bite of cake.'
I snorted so hard at my mom’s joke about the dog that the dog looked at me like I was the problem.
I huffed at my friend like I was about to punch him after he said, 'I just ate a whole sandwich for breakfast.'
