A giggle is a short burst of laughter that often sounds like a happy, snorting sound.
When people say "I couldn't help but giggle" they usually mean they found something funny and it surprised them or made them feel silly. This can happen when you see a silly joke, a humorous movie scene, or even just someone doing something goofy in front of you. If someone's making you laugh so hard that tears are coming to your eyes, they might say "I'm giggling uncontrollably!" It's also common for kids to giggle at silly things like cartoons or playing with friends.
A high-pitched, silly laugh.
To laugh gently or in a high-pitched voice; to laugh in a silly or giddy way.
Example: The jokes had them giggling like little girls all evening.
