Simultaneously having an online IM chat with several people while also sitting within conversation distance of said people in real life, especially on Facebook.

Random guy: Hey, what are you guys all laughing about?

Chatting guy: We're all multichatting on Facebook.
(gets a message)
Chatting guy: LOL, he totally does!
