Text Speak - What Does O Mean ?

[Sunk]

Someone sent me a message. Just the capital letter O

I’ve tried to look up what it means, but can’t find an answer.
I thought it might by a typo for OK, but was told it wasn’t a typo.
Can anyone enlighten me ?

I know lots of young’uns just put K for OK because it saves a millisecond of time. Perhaps O is just the new way of writing it. I don’t know though.

[ummmm]

Or 'Oh'

[Cloverjo]

Or it can mean a hug.

[jno]

OMG for atheists?

[chelle7272]

Often it means a hug.

hugs and kisses XOXO

[ummmm]

But most people have emojis for hugs etc.

[Sunk]

Thanks everyone ;-)

I would hope it is from someone you are intimately familiar with.

O is very suggestive.

[chelle7272]

Hugs or 'over' apparently:

I think the correct text response is "What the flip ?!"

[ummmm]

Or 'Oh...you stupid idiot'
