Yoyo mail ebc net tw

It seems like you're trying to communicate something using a combination of letters and abbreviations. Here's my attempt to decipher what you might be trying to say:

• "yoyo" could be a playful way of saying "hello" or "hi"
• "mail" might refer to email or sending a message
• "ebc" could be an abbreviation for "email" or "electronic business card"
• "net" might refer to the internet or a network
• "tw" could be an abbreviation for "tweet" or "Twitter"

Taking all these pieces together, I'm going to take a wild guess that you might be trying to say something like: "Hello, I'm sending you an email or a message on the internet, and I'd like to connect with you on Twitter!"

Am I close?
