when you giggle too hard and take the most gigantic sloppy messy yummy brown rainbow kaka in the toilet so hard that it recoils up your ass and makes everything brown
Breakdown:
• “Giggle” → implies the dog is more of a toy or accessory, often carried around and doted on, sometimes by people who treat it like a baby or fashion statement.
• “Shitter” → crude jab at the fact that small dogs can be prone to nervous or frequent pooping, especially indoors or during excitement.
So, “giggle shitter” =
A small, yappy dog often seen as useless, annoying, or overly coddled.
