When an email conversation between a man and a woman is going well and one asks to go to IM chat instead. Of course the reason is because it's faster but you can expect the conversation to turn to sex, somehow.
"Yeah, John and I have been emailing. He's really a cool dude, but now he wants to bump it up."
