"shellakybooky" means: Shellakybooky is a wonderfully quirky Irish word for a snail. It's the kind of term that makes you grin just saying it out loud — all wobbly.... This is a fairly neutral word with no inherent risk attached. There is no real cause for parental concern; it is descriptive vocabulary rather than something dangerous. If your child uses it, context will usually make the meaning clear. A brief, curious question about where they heard it is generally enough to know whether to follow up.
