galb - A tiny bit of giggling, like when you're trying not to laugh

A tiny bit of giggling, like when you're trying not to laugh but you fail at it, and your mom walks in and says, "What’s so funny?"

Galb when my brother told me my dog pooped on the couch.

Galb because my friend texted me a photo of a cat wearing sunglasses.

Galb when my teacher made me stay after class for no reason.
