Emoti-Whore

Somebody who, when in a conversation, repeatedly uses emoticons to express their thoughts and feelings. Rather than take the time to create a thought out response they use a series of emotions that leave you with absolutely no way to respond.

John - "Hey Shirley!"
Shirley - " :) "
John - " ..what's up?"
Shirley - " :\ "
John - "Wow, you're such an emoti-whore."
