Slacker received a one word text from one of his ex's. All it said was, "Hey." Now he doesn't know what to make of it.
Steve first guessed the word was 'pregnant.' When Steve found out what the word was, he said this is huge! He will do this to test the reactions of girls. If he gets a 'Hey!' back, he knows he is in. If she texts 'What?' back, he knows that he has no chance and the game is over. Steve totally thinks that Slacker's ex is trying to see if the window is till open.
What do you think it means? Why would she text him that?
