flash hey

Flash hey can also be referred to as a dry text to start a conversation. It would consist of just "hey" and nothing else. This is utilized by someone who is feeling sassy or annoyed with the other person. They want to talk to them but at the same time they are bothered that the other person did not initiate first.

Person 1: "Hey"
Person 2: "No need for the flash hey, I've been busy"
