what you doing
(Sends text to four girls) "what you doing"
Girl number two is first to respond with "not much, what about you?"
But before he can respond, girl number one (his preferred option) replies! She says "I'm free, wanna catch up?'
All he has to do now is tell girl number two he's tired and is going to bed and tell girl number one to come on over!
