Honestly, has anyone even heard this word used in an everyday conversation?

"I can say the word 'iono' and none of you will have a fucking clue what it means!"

used in instant messaging, "iono" is commonly known to mean "i don't know." you usually use it with stupid questions like "how do dogs have sex?"

nicole: how do dogs have sex?
me:oh my god iono.
