A made-up word that doesn't have a real meaning.
It's just a fun word to say and doesn't mean anything real.
Examples:
I like to say the word 'skios' because it sounds funny.
Let's make up a story about a skios.
Do you know what a skios looks like? Me neither!
I saw a skios at the park yesterday. It was invisible!
I have a pet skios at home. It's a pretend pet, but I love it.
I wish I could ride a skios to school. It would be so fast!
