hit send

To send something, such as an email or text message, via a computer or electronic device. A: "I can't do it!" B: "Oh, just hit send! You'll never know if she'll go out with you if you don't ask." Uh oh, I hit send before realizing that I had ticked "Reply All" by mistake. Now everyone is going to read my email complaining about the decision. You didn't get my email? Well, would you look at that—I never hit send.
