Sharesies

"Sharesies with all our friends!"

I didn't know the word, sharesies. I looked it up in dictionaries and found it in Urban Dictionary. 

_a unique way of saying that you will share something with someone 

Some twitter friends from US said "I first learned it on twitter. Not an east coast American expression."

And some twitter friends from UK said "I think it's British slang like 'going halvsies'."

According to my twitter friend from Australia, 

"Actually sharesies is used a lot here in Australia, kids use it, adults too sometimes, e.g. lunch with a friend and I want desert but too filling. I might say to my friend let's go sharesies on desert." 

Very interesting!
