Ariaism: sucks

Aria, having just been tucked in after a long day.

A: "Mama, I know who sucks."

M: "What?!"

A: "I know who sucks."

M: "I know who what?!"

A: "Sucks! I know who sucks."

M: "Sweetie, that's not a very nice word to say. It's not the worst word ever, but it's not a very pleasant word, so if we can find a different word to use, then that would be better. It's okay. You're not in trouble. Now, I want to know what you were thinking so, go ahead. Tell me who sucks."

A: "Satan. Satan sucks."

M: "Yes, sweetie, you are absolutely right. Satan DOES suck."
