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?"

a user called iono's catchphrase, they have said it over 400 times and iono is very cool. can be a convo starter and also the other user can repeat back saying that they are iono and it will cause chaos.

quick version of "i don't know". could be used to blow somebody off, or could be used if you genuinely "don't know".
