Oyster Definition

Alright, listen up, you oyster-sucking simpleton! This joke is all about being nasty, see? It takes something innocent, like a grandma, and then throws in something totally gross and shocking, like shoving shellfish where the sun don't shine and then slurping them back out. It's wrong, it's crude, and that's why some folks find it funny. Now, you probably think oysters are just for fancy restaurants, but guess what? They're also good for your health! High in zinc, which is probably something you're lacking if you think this joke is actually clever.
