look up any word, like fleek:
 
1.
Worthy of typing into your phone on the subway and posting on Twitter.
Me - "Someone just randomly texted me to say they are home from Croatia."

Someone else - "That sounds tweetworthy to me"

does the comment you are about to make follow the criteria of being tweet worthy (important).
"Joe, you can't just tweet anything."
"Why??"
"Just always remember I.I.T.W."
"What's that?"
"Is it tweet worthy, duh."
